The c:\windows\system32\logfiles\ show errors such as
connection dropped DefaultAppPool
xtier+netidentity SC status 401

Slow login issue after we installed ZENworks. ZENworks uses a Middle
Tier server to process its client requests. This Middle Tier server
uses IIS to process these requests.

It appears that IIS is the source of the slow login. The current error
we are seeing in the event log is with W3SVC A process serving
application pool 'DefaultAppPool' failed to respond to a ping. Event ID
# 1010 or 1013.

Any suggestions or performance configuration tips?
