Hi Experts

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.

Are you using Integrated or Forms based authentication for OWA?

im using the default config... integrated authentication.

The IIS site does not have a certificate (so Forms based authentication would not work).

thanks for ur help - i think i might have just realised whats happened.

The user account has a restriction that its only able to logon to a certain PC on the network.

I have just tried to take it off so that i can connect up using any PC and it seems to have done the trick.

I will test it further and let you know.

Hi All

i have checked this all out and it it turns out to be that due to the fact that i had restricted users to their own pc - this in turn basically locked them out of OWA if they used another PC.

I have removed their PC assignments within active directory and its fixed the problem.
Thanks for your help!
