Windows AFS Gui Login Error

We have seen some problems when attempting to obtain AFS Tokens using the Windows AFS client GUI. To work around this, you can use the Windows Powershell to get AFS Tokens:

1. Open a Powershell prompt
2. Type in the following:
   

   Code Block
   language powershell
   PS> cd "C:\Program Files\MIT\Kerberos\bin" PS> .\kinit <netid_or_guestid>@CORNELL.EDU

   (make sure to capitalize "CORNELL.EDU" ) . 
   You will be prompted for your netid or guestid password. The cursor will not move while you type in your password. Hit return when done.
3. Now type in the following:
   

   Code Block
   language powershell
   PS> cd "c:\Program Files\OpenAFS\Client\Program" PS> .\aklog -d

   you will see some debug output showing that you have successfully obtained AFS tokens.
4. The AFS GUI will now show your tokens.
