Known and discussed on here for weeks, Where have you been? Just kidding! I believe Citrix and M$ have posted fixes. I found that removing a registry key, and uninstalling the Update Rollup 1 for Windows 2000 Service Pack 4 (KB891861) did the trick. Since then, I believe citrix had rolled a fix for it. _____ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Minero, Hector B CIV K55 Sent: Monday, August 01, 2005 1:51 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] MS Security patches broke ICA Hello, after installaing the following MS Security patches, I cannot connect to the PS server via ICA.
