I have found numerious issues with the older 4.x clients and MPS 3.0 on W2k3. With the R02 patch I found that those clients would cause the server to BSOD. Patch 003 for R02 should address that issue. Apparently, Citrix does not officially support the DOS client anymore, so it's a "use it at your own risk" type of thing. _____ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Schneider, Chad M Sent: Friday, March 25, 2005 11:00 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Citrix DOS and MPS 3.0 I think I have found something.... I have several DOS Citrix client (4.3.XXX). They conect to applications fine on Xpe FR3/SP3, with necessary patches. They seem to connect to MPS 3.0 (no patches), they even seem to connect to MPS 3.0 with the rollup package 1 on it. It seems that once I put the MPS 3.0 rollup package 2 onto the server, DOS clients can no longer connect to Citrix applications. Anyone else heard of/seen this? Chad M.
