Terminal Services (Server not Found)

[Sunderwood]

Hi Guys,

Hope someone can help with this..

We run a split network here in terms of we have 50/50 Thin client devices and Desktops.

I came in this morning and no one could logon to a Terminal Client. It was throwing up errors about the Roaming profile?? So i first checked the desktops with the same user and they logged on fine with the correct profile.

I then thought it must be my terminal servers that were the problem so i looked into Terminal Services Manager and no servers were in my list. If i tried to add these servers it gave me an error "server not found".

So i rebooted all my TS servers and this seemed to solve the issue.... Until 1 hour later and it all happened again...

Please help...

Do they have the firewall enabled? Might sounds daft or simple but i have known the firewall to turn on randomly on Windows.

Hi,

Yer i have checked that we have the service disabled on servers anyway..

I'm just trying to Remove and Rejoin a server to the domain to see if the authentication has messed up somewhere..

What does the event log show?

[Sunderwood]

Its just spamming this error 10 times every second.

The description for Event ID ( 2453 ) in Source ( KIXTART ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: UserGetLocalGroups failed Error : Could not find domain controller for this domain. (0x995/2453).

But like i said everyone on a desktop is fine so the domain controllers are fine.

New one now..

Went to remove and rejoin it to the domain and the box is greyed out and it says underneath that:

Networking is not installed or is not installed properly??

Whats going on?? fine last week.. i have servers totally seperate from these servers doing it now.. print Servers, webservers???

Could it be a virus?

Hi

This could actually be a Microsoft licensing issue. Check to ensure the TS Cal's are being released after use. I have had a customer with the same type of problem.

Please let me know how you get on

Thanks,

I doubt it if it is happening to other servers that are not Terminal Servers.

DNS? ..

Well did a full scan on all my servers and found this new virus called "conficker" it's going to hit today. All seems ok but will see in the morning
