Access Windows Share under Network Service account

Question

I have two computers with Windows Server 2003. One computer has some shared folders on the network, and the other has a Windows Service (written in C#, running under the Network Service account) that needs to access those shared folders.

The following code works fine as a logged-in user, but throws an exception when executed under the Network Service account.

File.WriteAllText(@"C:\temp\temp.txt", File.ReadAllLines(@"\\NetworkServer\Test\test.txt")[0]);

The exception message is Logon failure: unknown user name or bad password. How do I get this code to work under the Network Service account? Is it a setting in Windows Server 2003, or do I need to add some code to this to make it work?

Answer 1

On the network share, you'll need to add permissions for the "Network Service" account on the server running the service.

Another option, is to create a domain account and then give that account read/write permission on the share, and then setup the service to "run as" the domain account.
