Unable to initialise admin dll (OSEnv)

You may see the following message,

"Unable to initialize admin dll (OSEnv)" or "Unable to gather user rights"

when starting Server Manager if a change has been made to any domain the user is a member of or if one of them has been deleted.

It may also be the result of connectivity problems where a domain is unavailable and the error can be caused by varying problems with the domain.

Check the possible domains the user is a member of has been modified, deleted or is unavailable.

Our code calls the Microsoft function GetComputerName() which is supposed to return the NetBIOS name of the local computer. See: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/sysinfo/base/getcomputername.asp.

Once it has the name, it uses it to call NetServerEnum() (another Microsoft call) to get the domain controllers for the computer's domain. See: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/netmgmt/netmgmt/netserverenum.asp.

If these functions fail, then an error is returned and the unable to gather user rights message is displayed.
