Fuji xerox DC-II 3005 have 027-516 error, how to solve?


[Cause] During the transfer using SMB of the scan to PC
feature, the SMB server could not be found.

[Remedy] Take one of the following actions, and try again:
Check the following to see if the destination SMB server
and the machine are set up properly for network
communications:
- Check the network cables are plugged in securely.
- Check the TCP/IP settings.
- Check communications of port 137 (UDP), port 138
(UDP), port 139 (TCP).
Check the following to see if the computer correctly
works as an SMB server.
- Check if the file sharing service for Microsoft
Network is activated.
- Check if [NetBIOS over TCP/IP] for TCP/IP
is activated.
- Check if the file sharing service (using
communication through port 137 (UDP), port 138
(UDP), and port 139 (TCP)) are authorized for the
Firewall settings.
For communications which exceed the subnet, check the
WINS server settings, and check if the server address
can be resolved correctly.
For Windows NT 4.0 Server/Workstation, use the
following steps to see if the NetBIOS interface device is
activated on the destination SMB server:
1. Select [Start] > [Settings] > [Control Panel].
2. Display [Services], then select [Messenger] service.
3. Select [Startup] > [Auto] > [OK], then select [Close].
4. Select [Devices] in the [Control Panel], then select

My print server cannot be reset to the factory default for some reason. I have tried holding the reset button for 10 secs, but without luck.


I have some devices where I have to hold the reset for 20 seconds. So try holding it longer. And make sure the print server is powered up when you do it.

Cannot connect server ...... client PC diplay this message


Can you PING the L230 device from the server? In other words, are you confident there is a clear IP path from server to device? Also, if you're running on XP, turn off the XP firewall as a test. If that works and you still want to run with the firewall on, then you'll need to specify specific ports to be opened up on your firewall or your domain's firewall policy. Those ports, as listed from NComputing's website are:
Port Exceptions
  • For L-series device connection
    • TCP: 27605, 27615, 3581, 3597, 3645, 3646
    • UDP: 1027, 1283, 3581
  • For vSpace registration
    • TCP Port 3630
    • Point to:
      • register.ncomputing.com
      • or 85.214.107.229
  • For vSpace Update
    • TCP Ports 20 & 21
    • Point to:
      • 70.182.176.102
      • or 81.169.173.128
      • or 81.169.173.128

  2. Click on Login, Advanced Setup, NAT, Virtual Server.
  3. Enter the port details and enable it as follows:
Private IP Private Port Type Public Port 192.168.2.x xxx TCP xxx 192.168.2.x xxx UDP xxx To access the application, you can open up the ports specific to the application in the special application, which is present in the router management screen as follows:

How to turn on a dhcp on a rca model dcm425 cable modem?


Hi there,
Enabling DHCP at the Client To enable the Windows NT DHCP client, you must log on as administrator at the Windows NT client.

Normally, you enable DHCP as part of the installation procedure for Microsoft TCP/IP, however, you can use this procedure if you have manually configured TCP/IP:
  1. Run Control Panel and choose Network.

    The Network Settings dialog box appears.
  2. Under Installed Network Software, select TCP/IP Protocol and then choose configure.

    The TCP/IP configuration dialog box appears.
  3. Select Enable Automatic DHCP Configuration.

    A Microsoft (MS) TCP/IP message appears, indicating that the DHCP Protocol attempts to configure the server automatically during system initialization.
  4. Choose Yes.

    A MS TCP/IP Configuration dialog box appears, displaying current TCP/IP configuration parameters. The IP Address and Subnet Mask boxes are not available (grayed out) and the manually configured values are no longer displayed.
  5. Choose OK to return to the Network Settings dialog box.
  6. Choose OK again.
  7. Shut down and restart the computer.
To enable DHCP on a Windows for Workgroups client if TCP/IP is not installed yet:
  1. Use Network Setup to install the MS TCP/IP-32 3.11 protocol.
  2. In the MS TCP/IP Configuration dialog box, select the Enable Automatic DHCP Configuration check box, and choose Continue.
  3. Restart the computer to initialize TCP/IP using DHCP.
To enable DHCP on a Windows for Workgroups client if TCP/IP is installed:
  1. To access the Network Drivers dialog box, run Network Setup.
  2. Select Microsoft TCP/IP-32 3.11, and then choose Setup.
  3. In the MS TCP/IP Configuration dialog box, select the Enable Automatic DHCP Configuration check box, and choose continue.

    A message box appears indicating that the configuration of DHCP overrides any values established locally.
  4. Choose Yes.
  5. To initialize TCP/IP using DHCP information, restart the computer.

I have two different domains that are connected via VPN connection through two routers. I can ping from domain to domain via IP address on clients and servers. However I can only do a net view command on...


So you verified ICMP traffic isn't blocked and it appears the servers allow the netBios traffic to pass.

On the client machine, check to make sure the windows print and file sharing is installed and the machine isn't blocking netBios traffic.

Make sure TCP ports 137,139, and 445 are open on the xp machine and any devices in between.

It's acting like the TCP data is being blocked by the client machine.

DP-300 Print Server Access Problem


Using a print server like this, you should not need to "browse" to find the printers. See what ip address has been assigned to the printer. Once you have the ip address, open a command prompt (start -> run -> cmd) and type:
ping <insert ip address>
ex: ping 192.168.0.24

See if you can ping the printer from each of your computers. If you can, great, install the new printer by adding a "local" printer at a new TCP/IP port with the IP address of your printer. If not, then you may have some routing issues.

Are all of the printers connected to the same switch? Do you have multiple "routers" on your network acting as DHCP servers?

Hope this helps.

Need to set port forwarding for filemaker to network


Port forwarding is a process that you set up on your router and is independent from your OS.
Go here, and select the router you are using. On the next page (after skipping that annoying ad) you will see a list for different software setup's. Depending on you router, you might find Filemaker in the list.
(I checked Linksys WRT54G, and found it.)
Filemaker Server and FileMaker Pro with TCP/IP are using port number 5003with both the UDP and TCP protocols when communicating via TCP/IP.
UDP is only used for the initial contact, all other TCP/IP communication is using TCP.

There is a good video description, which I highly recommend if you're new to this. You can find that here.

If you have more questions, come back here or head over to filemakertoday.com, which has an excellent forum and the guys know what they are talking about.

Good luck!

You may be behind a firewall or NAT. You can set an option that you are; if that still does not work, you may need to open some ports on the firewall.
Yahoo! Messenger uses a variety of ports.
Service Ports Chat & Messenger TCP Port 5050: Client Access only Insider/Room Lists TCP Port 80: Client Access only File Transfer TCP Port 80: Server Access.
Your ISP may block this port, as its used for web hosting.
You can change port in Messenger, Preferences, File Transfer. Voice Chat UDP 5000-5010
TCP 5000-5001: Client Access
If UDP Fails, TCP will be used instead, see below. WebCam TCP Port 5100: Client Access Super Webcam TCP Port 5100: Server Access P2P Instant Messages TCP Port 5101: Server Access
PMs between Buddys may not use the Yahoo! Server, but this is not a requirement.

What is BOOTP/DHCP?


BOOTP stands for Bootstrap Protocol. DHCP stands for Dynamic Host Configuration Protocol. Both are mechanisms to dynamically assign an IP address for a TCP/IP client by the server. In this case, the Prestige 310 Internet Access Sharing Router is a BOOTP/DHCP server. Win95 and WinNT clients use DHCP to request an internal IP address, while WFW and WinSock clients use BOOTP. TCP/IP clients may specify their own IP or utilize BOOTP/DHCP to request an IP address.
