I used vbscript to map the network drive which base on user group membership. If users are under trusted domain, the logon script seem can't find the user groug in different domain, so that it can't map the network drive. I tried to launch "active directory user and computers" in domain A, I found domain B's user under what group membership. Pls advice. Thx !!

This can be done by inserting group of users from first domain into the group of users from second domain. Appropriate domain type of groups depend on the current status in group created. (Unfortunately you have not specify more detailed parameteres an that is why my answer is a clipped style one.) Regards Milos

Do you use universal groups (made for this situation)? Richard Mueller - MVP Directory Services

only use domain local group and global group. no universal groups

This link explains when and how to use universal groups: http://technet.microsoft.com/en-us/library/cc755692(WS.10).aspx Richard Mueller - MVP Directory Services

So strange, I can't view the group in "member of" field if users are trusted domain.

Hi, I would like suggest you try the following two workarounds: 1. Add those users in the trusted domain to the local group. 2. Make those users as Use Universal group' members.

Thx your response, but i think item 1 is not a appropriate solution.
