terminal services session haijacked?

[CablingPro]

From one of my Win98 clients I'm attempting to connect to multiple W2K boxes running microsoft's terminal services.
No matter if I use TS client or the web-based client I get the same result; as soon as i connect to "my" server a message pops up :"This is a private system. Unauthorized use is strictly prohibited", then I get a logon prompt which doesn't accept my username/password combination. It appears as though I'm connected to someone else's server ???
I've checked my IP settings (DNS) and all looks OK, the client is set for DHCP, and it obtains the right numbers. Still, I can't seems to connect neither to any local TS servers nor the ones on the Internet.
Any clues? thanks

if you're not sure you're getting to the correct server, enter the exact IP in the TS client window instead of the host name when connecting.

When I'm using TS client connection manager I have to specify an IP address of TS server, otherwise I wouldn't be able to create new connection.

Then you most likely have a WINS or DNS issue, even though I know you say it's correct. If you ping the TS box by name, do you get the correct IP? How about if you ping it by FQDN?
