I have a problem on a new exchange server. Its been running fine for 2 weeks and now all of a sudden when some of my users are accessing their emails using Exchange 2003 OWA & Internet Explorer 6 (SP2) they get an error message stating "HTTP 500 - Internal Server Error".
I have diabled the firendly error messages on the browser and i get: "The Local Security Authority cannot be contacted".
I am running Exchange 2003 in a Active Directory environment and The Exchange server is a Global Catalog Server (Domain Controller).
The server o/s is Windows server 2003 SP2.
I have had a look at the Event Viewer however there are no errors showing up on it - which seems very strange!
I have had a look at a few posts on EE but cant find a solution - can anyone help please?
Thanks in advance for your help.
