Good luck... Not exactly sure where it's going yet, but I'm working on a tool that will tell me what groups a user belongs to on various domains as well as locally.

Sounds like a good tool to have. I saw the link to the sample you posted and it looks promising as the way to go. I'd be interested to see what comes of this! Did you look at Kevin's suggestion for using WScript.Network? Seems simple enough but I don't know how it would behave in your case.

I have a feeling that's just a wrapper around the NetWkstaGetInfo and NetWkstaUserGetInfo API calls, and they're giving me exactly the info needed, yep. -- ..NET: It's About Trust! http://vfred.mvps.org Customer Hatred Knows No Bounds at MSFT ClassicVB Users Regroup! comp.lang.basic.visual.misc Free usenet access at http://www.eternal-september.org

Here's what I did with Kevin's example, to add to my arsenal of DrivesFoldersFiles_Functions.bas: Function bUserIsLocalLogin() As Boolean Dim oWS_Network Set oWS_Network = CreateObject("WScript.Network") bUserIsLocalLogin = (oWS_Network.UserDomain = oWS_Network.ComputerName) End Function -- Garry Free usenet access at http://www.eternal-september.org ClassicVB Users Regroup! comp.lang.basic.visual.misc

I'm leary of ever relying on WSH when there's an API that'll do the job, though. You can achieve those same results using the NetWksta sample I pointed to earlier. -- ..NET: It's About Trust! http://vfred.mvps.org Customer Hatred Knows No Bounds at MSFT ClassicVB Users Regroup! comp.lang.basic.visual.misc Free usenet access at http://www.eternal-september.org |
