[Lilux-help] A windows question: joining XP to a samba 3.0 domain

[Sorry to ask a Windows question on the list...] This weekend we upgraded the Linuxstuff to newer versions of the Software (new Windows XP on the client, new SuSE 9.1 on client and server). SuSE 9.1 has samba 3.0 whereas 8.2, that we used before, had samba 2.0. All went fine until the very end. After cloning our newly set up client to the 9 others we noticed that we could no longer join the domain: Whenever we tried to join the domain we got the following error: "Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again" However, no shares were mapped when this message was displayed (we checked by looking at "My Computer" at client, and also by doing a smbstatus on the server... Or could there be hidden "connections" that show up at different places?) Multiple reboots didn't help either. Changing the domain name on the server didn't help (INTERNETSTUFFEN). First putting the clients into a workgroup with the same name (INTERNETSTUFFEN) before joining the domain didn't help either. We had kept one of the old clients as a "backup" on the XP version from last summer, and that client could still leave and join the domain without any problems whatsoever. Has anybody come accross a similar problem, and found a solution? Thanks, Alain
