I have a terminal server which is 2003. From yesterday, sometimes users can
remote desktop to this server but most time they fail. Network looks running
well. I can access shared folder on the terminal server. I don't see any
error in Event Viewer. Anyone can help me on this? Thanks a lot
 
The users receive what error....

Error is:

The Client Could not establish a connetion to the remote Computer
The mostly like causes for this error are:
1) Remote Connections might not be enabled at the remote computer
2)The maximum number of connections was exceeded at the remote computer
3) A network error occurred while establishing the connection

Have you checked the number of allowed connections in the Network
Adapter tab of the rdp-tcp properties?

Should I be concerned with this? :)

Netstat:
TCP server:3389 ip-122-152-181-170.asianetcom.net:32745
SYN_RECEIVED
TCP server:3389 irqfdsl-374.ontera.net:40772 ESTABLISHED

The ontera.net connection is mine and the asianetcom.net is from HongKong
and definately has no business in the listing. The user also received a lot
of spam over the weekend I guess this server is a bot server now? I am
looking into the issue further.

I'm thinking if it could be a problem of licensing. It looks like: a desktop
can remote desktop to the terminal server when it is the first time this
desktop remote to the terminal server. After that fail.

I solved my problem. After changing many security problems and blocking the
person trying to connect to server remotely I applied all available updates
including SP2, now I can connect without issues.? I still do not know what
the original issue was, however works after the updates.

I will have the users all change their passwords tomorrow just encase.

I find out that if I delete the subkey of HKEY_LOCAL_MACHINE - Software
-Microsoft - MSLicensing -Store (from client side), I am able to remote
desktop to the termianl server. I try it on serveral desktops. It works. Hope
it is the solution. But don't know the reason.

Thank you everyone for your replying

This means your licensing server is not able to hand out a permenant
license. Make sure, on that key, that Users have full control. They
probably do not.
