User.Principal.GetGroups() lookup wrong DC

Hello,

I work for a customer whose program makes a query on the groups of an AD. Until the time the DC was changed, the query with GetGroups() ran without problems. After the change GetGroups() points to a wrong DC address. Does anyone know where this old value comes from ? If I call GetGroups with context it works. I need this information for the external service provider that takes care of the AD.
Thanks a lot

    Hi @André Hagemann

    If you use the nslookup xxxxx.xx where xxxxx.xx is your domain, do you recieve the IP address of the new DC or the old one? If you receive the old DC, you need to change your DNS setup.

    The UserPrincipal.GetGroups() should return the groups of the new DC.
