Until recently, I had no trouble, except drive mappings in logon script
did not work under SDL, with the scenario described below (with NT). But
recently we upgraded our PDC to Windows 2000 and while using a Windows 2000
client, which worked fine with a NT PDC. Then I began receiving a 1311 error
- There are currently no logon servers available to service the logon
request. SDL also broke. Anyone have a better experience?
