RDP problem when application mode (Win2K3)

[Guest Steve Roy]

Hi !

sorry for my english, i'm french speaking.

This is a weird problem !

 

We have a (Server A) Win2K3 Ent. SP1 french TS where client can connect with

RDP without problem.

These client are:

1- Wyse terminal using RDP ver. 5.1

2- XP using RDP ver. 5.x

3- XP using RDP ver. 6

 

I installed similar server with Win2K3 Ent. SP1 french (Server B) with

latest hotfix like the first server (Server A).

 

Both TS are set to "application mode" and the client 1 and 2 (Wyse and RDP

5.x) cannot connect to the TS Server B, client 3 is OK. They received this

error message:

"Because of a security error, the client could not connect to the remote

computer. Verify that you are logged on to the network, and then try

connecting again".

 

The RDP setup on both server are identical and the LS (license server) is

the same for both servers. On the server B, if I uninstall "Terminal server"

service, so the server B is now set to administration mode (only 2 admin

connection), the client 1 and 2 can now connect. It's alway OK for the

client 3.

 

We found some case on microsoft web site, it was to remove some registry key

like "certificat", "certificatx509" on the TS ,we tried this without good

result.

 

Also, we think about communication problem between the TS and LS server so

we decided to try this: We used the 120 days trial when we install the TS

server, same problem so the problem is not between the TS and LS.

 

So... thanks for your help

Re: RDP problem when application mode (Win2K3)

 

I still think that it could be a licensing problem.

Which type of licenses did you install on the LS?

Have you checked if there is a free licenses available, or if your

client 3 still holds a valid license?

Have you checked the EventLog on Server B for any errors or

warnings?

Also run the lsview utility from the Resource Kit on Server B to

check that it can detect the Licensing Server.

Ans make sure that the licensing mode on server B matches the type

of licenses that you installed on the LS (Per User, or Per Device).
