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.

Packet loss slow internet dell


If you loose packet when you ping your router, is or your router or your network card who made the problem. Try to ping your router with an other computer. If you still lose packet is the router otherwise is you network card. When you know where's the problem you can change the faulty device.

Printer is offline


What type of printer are you having a problem with? Is it on and do you see any error messages on the printer? How is it connected to the computer? Do you have the driver installed? Some printers need to have the driver installed with a USB connection before moving to a network install. (For all-in-ones, the driver/software must be installed before you connect the data cable.)

If a wired connection, try new cables (fully seated) and different ports. If it is a USB connection, try a direct connection if the printer is connected to a USB hub or print server. Make sure that the cord is 6' or shorter. Check if other devices work. (I've seen a few computers loose their USB ports for no apparent reason. On desktops, try rebooting the computer and uninstalling the USB drivers and rebooting again. This is in the Device Manager for Windows machines. On a few laptops, sometimes removing the battery and the power adapter will reset the ports.)

For network connections, make sure that your network is up and that you aren't getting signal loss issues (for wireless networks). Try a wired connection to check for network loss. To check a network, I tend to check a few points with the ping command. For Windows, launch the Command prompt and ping the numerical IP location of your router. Then ping the IP location of the DNS server. Can you see the printer on your list of network places. (The format for ping is
ping 192.168.1.1 or ping www.google.com followed by enter. The returned message will be either the time for a small packet of data to go to the location and return or a connection timed out.)

If you are losing your network connection, reboot your router and broadband modem. (Try rebooting the router first.) Make sure your firewall is not blocking access to the printer.

I hope this helps. Please write back for more information with specifics for your printer.

My router is on but it seems so slow. i keep getting randomly disconnected, the connection is terrible and even when i turn it off for 30 seconds and on again it stills acts up, any ideas?


ping your router with a packet length strength. To do the ping test, go to Start-Run and type CMD and hit enter. Then, in the Command Prompt Window type in the following

ping 192.168.0.1 -l 30000 9

I suppose the 192.168.0.1 will be the default gateway of your router. To check which is the default gateway of your router you can double click the connection icon on your PC, and click the Support tab. You'll see the degault gateway IP third on the list.

Now, if it pings back all three times with times below 100ms then ok. If it doesnt then reduce the ping length to 20000, if again you have losses then reduce it again to 10000. If the ping loses packets and response is slow you'll probably need a new power cord.
If the pinging is ok at 30k then you'll probably need to change the LAN cable that leads from your internet connection onto the wifi router.
To verify this, run this command

ping google.com -l 10000 and see if you have any losses. If you do have losses, then do a ping like this

ping google.com -l 32000 if you again have losses in the ping then you'll need to change your LAN cable because the 32kb packet is almost a standard size of packets and it should have no problems to get through the router, unless the LAN cable is bad.

Hope this helps. Please vote a Thumbs Up if you found this useful and informative.

Check whether the packets are routed properly. Check Ping for your laptop and desktop. If any packet loss is there check the configuration .

I have two RVS 4000 routers with pulic IP's connected VPN to each other. The Ip's on each end are 192.168.1.1 and 192.168.2.1. No firewalls. I cannot see the ping request on other network ???? I can see...


non public ips mean the 192.168.x.x. addresses you are referring to ... since they form a virtual private network it is normal .. see if ping protocol is disabled ..the other router just discarding the ping packets... you may have to check the route a packet is taking without VPN ...it can be complex without a network diagram.

Wi Fi fine, ISP fine, no internet via LAN connection though.


Make sure your firewall is not blocking your ability to go to websites. I saw this the other day, somehow the users firewall was set to block all internet traffic out of the computer.
