Win2003 Terminal Services connection problem

Posted on 2007-08-07
Last Modified: 2013-11-05
System : Windows 2003 Server behind a firewall with 2 Nics on server.
There is no sleep settings on the NICs
Terminal Service for in-house network works all the time.
Remote terminal service location works fine for a while and randomly fails(different times and lengths of time before issue reoccurs). To allow remote location terminal service connection to be restored we must disable then re-enable the inbound NIC for terminal services.
We have tried swapping the NICs but the same issue reoccurs. We have taken the server down to one NIC and the same thing occurs. We setup bi-weekly reboots of the server an  this does not fix the issue either.

This is not a new problem for our customer. This problem existed before our company took over support for this customer. We are new network admins for this customer and have changed out the routers / server / switches at both locations.

Any insight will be greatly appreciated.

    If you have the gateway setted in each NIC, probably is better have only one gateway e some static route.

    This article describes how to configure a default gateway, Microsoft Windows behavior when there are multiple default gateways configured on different interfaces, and dead gateway detection.

    Both NIC's have the same gateway.

    I dont'rt have enought information about your networks...

    Because the TCP/IP protocol only uses a single default route in the routing table at any one time for default route traffic, default gateways configured on multiple interfaces that are connected to disjoint networks can produce confusing or undesirable results
     Configure a default gateway on the interface that is connected to the network with the largest number of routes. In most configurations of disjoint networks, the network with the largest number of routes is the Internet.
     Do not configure a default gateway on any other interface. Instead use static routes or routing protocols to add the routes that summarize the address space of the other disjoint networks to the local IP routing table.

    Accepted Solution

    Looked over your suggestion and We all ready have static routes in place. This problem still happens even when there is only 1 NIC enabled in the system.

    I had strange terminal server problem with a broadcom nic on a Dell server, the solution was install the last driver... (excluding tcpip misconfiguration the problem should be the Nic card or a ISP problem)
