Entlib June 2005 Logging block stopped working

Hi,

We use the EntLib June 2005 release for logging. The Databasesink and
Eventlog sinks are used as the log sinks. The application runs on a
webfarm with nested sites. My application structure is as shown below.

DefaultWebsite
-------------------> My application (with logging)
-----------------------------------> Webservice location (with
logging)

The logging used to happen from both the My application and the
Webservice. Logging has now stopped at the Webservice application. I
am not sure if any security patching created trouble. The cumulative
service patches were installed, including patches to the xml core
(elevation of rights issue patch). I am not able to restore logging
from the webservices.

Could someone help me here? Thanks in advance.

Best regards
Anand
