Has anyone seen this? When a User logs into Webmail they sparatically receive the error FAILED TO CONNECT TO T HE MICROSOFT EXCHANGE SERVER <SERVER NAME> I know that when a user logs into Webmail, a temp file is created and when they log out these files are supposed to disappear. (I think this was fixed with exchange service pack 2 or 3). In our case, the temp files are piling up and not disappearing. We are running Windows 2000 with Exchange 5.5 sp4 on 2 webmail servers and are seeing the same thing on both. The only way to beat this problem that I have found so far is to schedule an IIS service restart every other day. Any help would be appreciated. Thanks, Todd t@xxxxxxx
