RDP and Trend Micro

[jdam]

Hi all.

I am running terminal services on 2003 enterprise in application mode. I have 2 terminal servers with NLB and Session directory hosted on another server. I have about 20-30 users logging in throughout the day. Usually 15 - 20 concurrent users at any one time.

Here is my issue.

I have 1 client with 3 users inside there office that connect to me. They have 2000 and XP. Their environment is 2000 server SBS. No firewall, only NAT router. They are running Trend Micro AV from the server to the client machines.

They complain of difficulty connecting to my servers, connections dropping off, sessions freezing, black screen when minimizing the session window. Their IT service provider is insistant the issue is not in their environment but mine. None of my other clients have this kind of connection issues.

Any suggestions? Does Trend Micro include a Firewall service in the package (I don't know the version of Trend they are running, probably something a little older)?

Version 7 has a built in Firewall option.

Have you checked to make sure that fragmentation of packets is not causing the drops?

 

[jdam]

Fragmentation on the server side or in the client environment? How would I check for or monitor that?

Got an answer on the 2003 server forum. Thanks for all your help guys.
