Error ‘440 Login Timeout’ with Outlook Web Access

Hello,

I today wanted to deploy the FTP services for IIS on a Windows Server 2003 SP1 (standard).

The installation didn’t perform well and restarting the IIS with iisreset failed at starting.

Then I realized that now I get an error ‘440 Login Timeout’ when I try to browse the Outlook Web Access (Exchange 2003).

Getting the mails from Outlook or mobile devices work properly, only the webmail is broken.

I have been searching a lot but I cannot figure out what could be wrong. Also, I followed the MS tutorial at http://support.microsoft.com/kb/917686 but it didn’t help neither.

Would someone have a hint to my problem?

Thanks by advance!
