Important configuration issue: You must overwrite the proxy server password in the configuration wizard

If you are using a proxy server that requires username/password authentication, the WSUS server may fail to synchronize updates if you do not overwrite the proxy server password when running the WSUS Server Configuration Wizard. Since the configuration wizard is launched automatically at the end of setup, this problem can cause synchronization errors after you upgrade from an older version of WSUS to WSUS 3.0.

You can avoid this problem by cancelling the Configuration Wizard after upgrade, or by reentering the correct proxy password when the wizard runs. To recover from this problem once it has occurred, go to “Options/Update Source and Proxy Server”, reenter the proxy password, and save the setting.
