We have an SBS 2008 Server using RWW. Recently we began to have intermittent RWW login problems.
Everyone can login to the RWW portal page fine and select their computer to login to. We are then prompted for our credentials again (at the bottom, the domain is the correct domain.) The first attempt always fails with a general failure to authenticate. Sometimes the second attempt will work. If the second attempt doesnt work, all subsequent attempts will fail for an unknown period of time.
If we attempt to connect a few hours later, it may work and it may not work.
Under IIS | Sites | SBS Web Apps | RPC - The authentication has both basic and Windows Authentication Enabled. Kernel Mode for Windows Authentication is disabled.
Event viewer is not logging any errors in Application, System or Security.
We are having Problems on different OS's - XP Vista and Windows 7.
Certificate is self-issued.
