If you are using Active Directory for your SOLIDWORKS Enterprise PDM authentication, and you have A LOT of user accounts within EPDM, expanding the “Users” node within the administration tool can take longer than a story from Great Aunt Eleanor about the advantages of dual ranked RDIMMs over single ranked UDIMMs.
The wait is caused by EPDM checking each user’s status against Active Directory.
Instead of expanding the users node; right mouse button click on “Users” and select OPEN to trigger a users dialog. This is much quicker, since it by-passes the bulk-authentication step.
As a side note, if you have less than 25 users, and it is taking more than five seconds to authenticate those users, you may have some network health issues that may need addressing.
