Environment.CurrentDirectory isn't working for Windows Services

The admin's decided to run my Windows Service under the NetworkService account to improve security. The problem is that where I thought I was saving temporary files to the directory of my application using Environment.CurrentDirectory , it was retrieving C:\windows\system32 ???? I therefore had to change the way I retrieved the local directory to: string directory = new FileInfo(Assembly.GetExecutingAssembly().Location).DirectoryName; This means that any logging files that used to be xxx.log, now have to give their full path.
