Today was working on a users problem with getting trust issues on Windows 2008 SBS network. User said it started earlier in the week. But today for the first time, he said he rebooted his computer while connected to the network and it just sat at the Windows 7 "Please Wait" prompt for 20 minutes. He then rebooted and it went for 5 minutes. He then undocked from his workstation and it still would not get past "Please Wait". He then tried turning off his WiFi connection, isolating him from the network and it got past that prompt within a minute. He was able to log into the system using his cache credentials and then connect to the network and all worked fine. Could get to network resources and Outlook. I am looking into the other problem.
But tonight at 6:00 a user called and said she had to reboot her computer, also a Windows 7 notebook, but it would not get past the "Please Wait" screen. She waited 15 min. She rebooted and still the same. Called me and I had her disconnect from the network, turn off her wifi and she was able to connect. So now its on two machines.
Seems like something that the workstation is waiting for when connected to the network, like the domain controller or policy manager, etc. Will go in early in the AM, but never had this problem before.
on a similar issue we had, it was related to ipv6 settings. check if ipv6 is enabled on the clients? if so, is it enabled on the server too?
if the server is not set to use ipv6, disable on the client and see if it fixes for you.
