Application center 2000 SP2 on windows 2003 behind ISA 2004 Enterp

| Hi,
we have the following setup:
2 x ISA 2004 enterprise edition (nlb) used as reverse proxies
3 x windows 2003 (no SP) with application center 2000 SP2
The application center servers host a variety of com+ and dotnet
applications. we are regulary recieving errors 1009 and 1011 in the event
log. We checked the knowledge base and found the exact same symptoms in
article 895983 (Event ID: 1011 and Event ID: 1009 occur when you use an ISA
Server cluster in front of an Application Center 2000 cluster). However the
proposed fix seems to apply only to Application Center with SP1. In the
article it is mentioned that rffilext.dll must be version 1.0.441.20 however
we have version 1.0.780.0 (sP2). We entered the following command as
suggested in the KB "mdutil.exe set AppCenter/Cluster -prop 57624 -dtype
DWORD -utype 200 -value 0" but we are still encountering the same problem.
The only way these events disappear is if we disble keepalives on IIS, but
this incurrs a performance overhead + some applications typically streaming
large images and using the response.flush command take up 100% cpu usage on
the webserver (and application center dll would be taking up the cpu
resources).
Any solution?
Thanks & REgards,
Mark

| The dll causing full cpu loading is msatq.dll
