=Problem:=

Attempting to access another computer from My Network Places that is on a workgroup (not domain) results in the following error:

"\\ is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. Logon failure: the user has not been granted the requested logon type at this computer."

=Solution:=

 Download the following and install it

Windows Server 2003 Resource Kit Tools @http://go.microsoft.com/fwlink/?LinkId=4544

after installation is complete, click on: Start, All [|Programs], Windows Resource Kit Tools, Command Shell

Then enter the following commands. (Attention: they are case sensitive.)

net user guest /active:yes ntrights +r SeNetworkLogonRight -u Guest ntrights -r SeDenyNetworkLogonRight -u Guest

The first command enables network access for Guest, the two subsequent ones change two different policies to allow network access for Guest.
