Also ensure that the identity under which your webservice is running has
write permissions to the folder
"c:\inetpub\wwwroot\log4net_webservice_prototype\".

Have you specified a <lockingModel> on the RollingFileAppender? The
default locking model takes an exclusive lock on the output file. Do you
have multiple processes writing to the same log file? As it is a web
service are you using a web garden or other form of clustering or
pooling? Do you have some other process that would be preventing a write
lock from being obtained on the file.
If you have multiple processes using the same output file you can
configure the RollingFileAppender to use the minimal locking model which
only opens the file to write the message and then closes it. Add the
following to your RollingFileAppender config:
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
Cheers,

Subject: logging web services
I am trying to log from a web service, and am getting errors
about acquiring locks on the output file. What extra steps
need to be performed to use log4net to log web services? Here
is my internal debugging:
log4net:ERROR [RollingFileAppender] Unable to acquire lock on
file
c:\inetpub\wwwroot\log4net_webservice_prototype\arc_prototype.
Form1.log. Access to the path
"c:\inetpub\wwwroot\log4net_webservice_prototype\arc_prototype
