IIS 7.5 does not write NLog (maybe due to permissions)?

Question

I have my webserver (IIS 7.5) on windows server 2008 R2. The Nlog on my server does not write any log files. To resolve the issue I have tried

1. Full rights to the log directory for NLog
2. Switched off IE enhanced Security

I can see that my AppPool is started in task manager - processes with the DefaultAppPool user. I have tried everything I know and can't understand what could be wrong. Please help.

My problem was entirely different. I found via dependency walker that some windows DLLs were missing from my machine
