Question : The name on the security certificate is invalid or does not match the name of the site

Hi ,
I recently renewed our Thwate certificate for OWA. We use ISA 2004 and Exchange 2007, installed the new cert in the personal store on both ISA and IIS(Exchange) servers. Now when I load the email application, Outlook, 200,03/07, all clients are seeing a security alert.
The name on the security certificate is invalid or does not match the name of the site.
exchange server is called mailserver, cert refers to webmail.mydomain.com .
The following is shown in the exchange shell
CB7E52C6C845B1893C21848656FE91E4CDA1CD07  IP.W.      CN=webmail.mydomain.com..
EF8259C29DE61E59B8D38BA144C43ED2FD96E6F8  .....      CN=www.thawte.com, OU=I..
79AC2AFE0B5D4819124815C2012FC5FE514E7F0E  .....      CN=mailserver
C3FA1BABA0BDFA04600A8260A718F0609603E0DE  .....      CN=mailserver

Webmail and OMA is up and running, I want to get rid of this security alert for clients,
Any suggestions appreciated,
Thanks,

First thing I would try is to run your app on a regular, non TS, 64-bit 2008 Server. Does it work?
If it does, the issue may be on the TS side of things.
In this case, try opening a command prompt before running the app and typing CHANGE USER /INSTALL. Now run it. Does it work?
Also, does it work if I am a member of the local administrators group? If it does, the issue is permissions and you can track the issue using Process Monitor from Microsoft (free).
