How do I fix server error 8004849


This is from Microsoft:-

If you receive Server Error: 0x80048849 and/ or 0x80048820 in Windows Live Mail at home or while you're in your regular network, it may be due to the setting of the MTU (Maximum Transmission Unit) on the mail client.
If you get this synchronization error at a coffee shop, airport or a place from where you don't usually connect to the internet, we suggest synchronizing mail on your regular internet connection.
When the MTU setting on the mail client is larger than the MTU settings configured on network devices between your mail client and the mail client servers, some data packets may be lost, causing mail synchronization to fail.
Follow the steps given below to fix synchronization errors due to mismatched MTU settings:
Determine the MTU setting on your network device
Apply the MTU setting to your mail client
Determine the MTU setting on your network device
This is a trial and error process, and will be different for each user. You may have to repeat the procedure below a few times, before you can find out the MTU setting of your network device. Follow the steps below:
Open command prompt
Click Start ? Run ? Type cmd
In the Command Prompt Window, type in the following:
Ping <Mail server address> -f -l 1500
Notes:
The <Mail server address> is the IP address of the mail server that you are unable to synchronize with.
For Hotmail, 65.55.33.106 is the IP address for DeltaSync (mail.services.live.com).In this document we will be using this IP address as an example.
In the -l 1500, 1500 is the max MTU for Ethernet connections.
You may get an error like this (100% packet loss):
C:\Users\username>ping 65.55.33.106 -f -l 1500
Pinging 65.55.33.106 with 1500 bytes of data:
Packet needs to be fragmented but DF set.
Packet needs to be fragmented but DF set.
Packet needs to be fragmented but DF set.
Packet needs to be fragmented but DF set.
Ping statistics for 65.55.33.106:
Packets: Sent = 4, Received = 0, Lost = 4 (100% loss)
If you received the error above, subtract 28 from the 1500 bytes of data. In the Command Prompt Window, type in the following:
Ping <Mail server address> -f -l 1472
If you get a 0% Packet Loss with 1472, it means the MTU setting of your configured network is 1472
Note: If you continue to receive the error described in (b) above, repeat the above steps by subtracting 28 from 1472 bytes of data. Repeat these steps until you get a message for 0% packet loss. If you were able to communicate with the mail server at an MTU size of 1424, you will receive the following:
C:\Users\username>ping 65.55.33.106 -f -l 1424
Pinging 65.55.33.106 with 1424 bytes of data:
Reply from 65.55.33.106: bytes=1424 time=230ms TTL=241
Reply from 65.55.33.106: bytes=1424 time=196ms TTL=241
Reply from 65.55.33.106: bytes=1424 time=162ms TTL=241
Reply from 65.55.33.106: bytes=1424 time=163ms TTL=241
Ping statistics for 65.55.33.106:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss)
Approximate round trip times in milli-seconds:
Minimum = 162ms, Maximum = 230ms, Average = 187ms
Apply the MTU setting to your mail client
Follow the steps below:
Open command prompt as administrator (you must be an admin on the computer)
Click Start ? Run ? Type cmd
In the Command Prompt Window, type in the following:
netsh int ip show int
You will receive a message similar to the following. Find the connection name that you use to connect to the internet and note the Idx value
C:\Users\Username>netsh int ip show int
Idx Met MTU State Name
--- ---------- ---------- ------------ ---------------------------
1 50 1472 connected Loopback Pseudo-Interface 1
11 20 1472 connected Local Area Connection
To apply the correct MTU setting on your mail client, type the following in command prompt:
netsh int ip set interface <Idx value> mtu= <MTU setting of your router> store=persistent
Press Enter
For example, if the correct MTU setting was 1424 and Idx value of your connection was 11, you will type:
netsh int ip set interface 11 mtu=1424 store=persistent
If (c ) was successful, you will receive the confirmation message "Ok"
Exit command prompt
Restart your computer
Open WL Mail and see if the issue persists.

Cannot communicate with Primary DNS


try pinging the DNS server's IP Address

the command line is

ping (ur server's ip) xxx.xx.x.x

if you get a response then the problem is that you are not in the same subnet. Call your ISP and they will tell you what to do next

Dell pc wont pick up internet


There are wide issues that may occur, with a issue with "dell pc wont pick up internet" is very general, so please be specific, however i went over most issue step by step, hope this help
Make sure you have the correct IP scheme for your network. This would include the:
IP Address
Subnet Mask
Default Gateway
DNS Servers
Click on start, run, type in cmd, The run IPCONFIG /ALL. A sample where a router is used is in the following graphic.
IP Address:
If you have a router, common examples would be:
192.168.0.x, 192.168.1.x or 10.0.0.x
If you are directly connect to your DSL or Cable Modem, you should have an IP address that would correspond to something from your ISP.
What you don't want to have is something like 169.254.x.x. This means you are not getting and IP address assigned and needs to be resolved first.
Subnet Mask:
Also make sure you have the correct Subnet Mask. Most commonly this would be 255.255.255.0
DNS Servers:
Make sure you have the correct DNS Servers.
Sometimes this is the IP address of your router, so it would be the same as the Gateway IP.
Sometimes (as in this example), it is the actual DNS servers used by the ISP.
Possible causes for not getting an IP address assigned are:
1. Defective cable, network card or port on the router. Make sure you are using all known working components.
2. Your router is not configured for DHCP (which would automatically be assigning IP addresses).
This and can be done from that same command prompt you used to run IPCONFIG
2. Try pinging the router's IP address
e.g. ping 192.168.1.1
If you get a reply, then your connection to the router is working.
If you don't get a reply, then you need to double check your network card, cable, port on the router. You might also see if any other computers on the network can do the same.

3. Try pinging an external site by IP address
e.g. ping 4.2.2.1
If you get a reply, then you have a connection to the Internet.
If you don't get a reply, there are several things you can try:
1. Double check that the router is connecting to the Internet. Typically you can access the router through your web browser and check it's status.
2. Take the power off your DSL/Cable modem and Router. Plug the modem back in a wait a minute or so. Plug the router back in and wait a minute or so. Then restart your computer.
3. WINSOCK Fix - It is possible that the WINSOCK Registry entries have gotten corrupted. This is getting to be a more common problem. See WINSOCK FIX for clean ones you can download

4. Try pinging an external site by Name
e.g. ping www.yahoo.com
If you get a reply, then you have a connection to the Internet and DNS is working
If you don't get a reply, there are several things you can try:
1. Double check your DNS entries
2. You many need to use the same DNS IP address that your ISP or Router is using.
3. On rare occasions your ISP has problems with their DNS servers. But that is rare in comparison to misconfigured computers.

If your PING tests work but you are having problems browsing sites on the Internet
1. If you could ping external sites by both IP address and Name, but cannot browse the web, likely your web browser is misconfigured.
2. Double check that you don't have an incorrect or not needed Proxy server assigned.
For the Internet Explorer - Tools / Internet Options / Connections tab / LAN settings button. Uncheck both Automatically detect settings and Use a proxy server for your LAN.

Internet connection problems


Troubleshooting Internet Connection Problems The purpose of this section is to give general tips
on troubleshooting your Internet Connection

While there are many possible configurations, I'll try and cover the most common ones.

Making Sure You Have Correct IP Information
Basic PING Tests
Browser Configuration

Making Sure You Have Correct IP Information 1. Make sure you have the correct IP scheme for your network. This would include the:
  • IP Address
  • Subnet Mask
  • Default Gateway
  • DNS Servers
2. There are a few ways you can see what IP addresses are being assigned.
But generally for:Win9x - Start / Run / command
Windows2000/XP/Vista - Start / Run / cmd
The run IPCONFIG /ALL. A sample where a router is used is in the following graphic.
ipconfig.jpg 3. IP Address:
If you have a router, common examples would be:
192.168.0.x, 192.168.1.x or 10.0.0.xIf you are directly connect to your DSL or Cable Modem, you should have an IP address that would correspond to something from your ISP.
What you don't want to have is something like 169.254.x.x. This means you are not getting and IP address assigned and needs to be resolved first.
4. Subnet Mask:
Also make sure you have the correct Subnet Mask. Most commonly this would be 255.255.255.0 5. Default Gateway:
Make sure you have the correct Default Gateway IP address.
With a router, this is typically the IP address of your router. 6. DNS Servers:
Make sure you have the correct DNS Servers. Sometimes this is the IP address of your router, so it would be the same as the Gateway IP.
Sometimes (as in this example), it is the actual DNS servers used by the ISP.
7. Possible causes for not getting an IP address assigned are:1. Defective cable, network card or port on the router. Make sure you are using all known working components.
2. Your router is not configured for DHCP (which would automatically be assigning IP addresses).
But you need to have this correct before proceeding.

I have the HERMO packard bell model. I can hardly access internet and the sound is not heard. Please hhelp


For internet
Resolution:
First check ipaddress
Click Start -run- type cmd hit enter for XP or Start -search-type cmd hit enter in Vista. On the DOS black screen after the blinking cursor type ipconfig hit enter check the ipaddress if are getting ipaddress other than (169........) it is proper ipaddress for e.g 147.14.48.478
Ping the default gateway e.g ping 147.11.445.478 if you are able to get packets send 4 received 4 loss zero is with Internet explorer or operating system.
If unable to ping or getting 169..... ipaddress . you are having static ip address
On the black screen at the blinking cursor type ipconfig /release hit enter
then type ipconfig /renew hit enter .check ip address
Ping default gateway then ping www.google.com if you are able to get packets send 4 received 4 loss 0. Try connect to internet using internet explorer or other browser. if still unable to connect then issue with firewall or antivirus or IE corruption .
Create new administrative account in XP and do MSconfig .Restart the system and logon to new account and try connecting to internet.
If issue persist might have to repair IE or operating system as it is software issue or virus issue.
You can connect a different computer if you have one and check internet.
If unable to get any ipaddress or still getting static ip address ,reset modem or check ethernet cable ,do a hard reset on the internet modem.Shutdown and restart computer and check ipaddress then try connecting to internet.

NO sound : Check the sound driver .Try reinstalling sound drivers

Cant connect to the internet.


Click on Start and type CMD. Open CMD and type ipconfig. Check out the IP address V4 for the Local area ethernet adapter or wireless area adpater depending on wireless or wired connection. Any ip address other than of the class 169.254.x.x shoud be considered good. If you have an IP address is any other number other than the above you have a good IP address. to test the internet connectivity type PING www.google.com. If the results are Packets sent 4 Recieved 4 Lost 0 then the issue could be due to Internet Explorer bing corrupt or a firewall blocking the internet access. Power off the computer. Power on the system and as soon as you see the Dell logo please tap the F8 button 3 - 4 times. You'll get to teh Advanced Windows boot option screen. Select safe mode with networking and see if the internet works in the safe mode. If yes then it could be the firewall. Uninstall you antivirus and check.
