Hi, We have deployed the 11 client (with passthru enabled) to a bunch(large bunch) of xp workstations and started getting locked profiles. We believe these are the articles talking about it: http://support.citrix.com/article/ctx118226 http://support.microsoft.com/kb/969100 Our user logs confirm ssonsvr.exe is locking the profile. One of our techs says Microsoft says there may not be a client to correct this issue. I believe they are aware of the above citrix article. I have three questions. 1st - has anyone run into this with this client and gotten a "new" client to correct it? 2nd - has anyone run into this on a w2k3 server. we are just about to upgrade to this version and are holding off 3rd- is everyone going with the prefech work around Regards, Doug Stratton, Shared Service BC Service Desk Email: 77000@xxxxxxxxx Service Desk Tel: (250)387-7000
