I'm having a really goofy problem with RWW on a Windows Server 2008 SBS box. When a user tries to log in remotely to their computer, they will get prompted for their username and password in the typical pop-up box from Microsoft Internet Explorer. However, the credientials do not get accepted and the box reappears. If I reset IIS using the iisreset command, this problem goes away and the users can log in without an issue. However, the problem will eventually reapper. It seems to happen once or twice a day. It is important to note that RDP works without a problem throughout all of this.
What I've tried so far:
Installed SP2 for Server 2008 and subsequent updates.
Someone else suggested, " In Exchange under Outlook Anywhere i changed Client Authentication Method to NTML authentication. I think the problem is that you can not mix two authentication methods. Exchange and TS gateway is sharing the RPC directory under IIS and beacuse of that the same authentication method has to be used." So I tried this and it did not fix the issue.
