Why did several administrative tools stop working after I removed the Everyone group from the "Access this computer from the network" user right?

Navigate to the folder

%systemroot%SysvolSysvolDomainnamePoliciesMachineMicrosoftWindows NTSecedit

for the policy affecting the "Access this computer from the network" user right and locate and open the gpttmpl.inf file. To determine the correct policy, you'll need to identify the appropriate globally unique identifier (GUID) for the policy. You can determine a policy's GUID by opening the Active Directory Users and Computers snap-in, displaying the container's Properties dialog box, clicking the Group Policy tab, then viewing the policy's properties. Because the Active Directory Users and Computers snap-in might not be accessible, you'll probably have to manually view each policy's GUID to identify the correct Group Policy Object (GPO).

From the gpttmpl.inf file, copy everything after "SeInteractiveLogonRight=". The string of values will look similar to

SeInteractiveLogonRight = *S-1-5-32-550,*S-1-5-32-549,*S-1-5-32-548,*S-1-5-32-551,*S-1-5-32-544,*S-1-5-21-907700337-3330534744-2079332775-1003

Paste the string of values you copied from the SeInteractiveLogonRight line after the equals sign in the "SeNetworkLogonRight=" line in the gpttmpl.inf file.

Save the changes, then close the gpttmpl.inf file.

Locate and open the gpt.ini file at the following folder:

%systemroot%SysvolSysvolDomainnamePolicies

Increase the version number. For example, change

[General]Version=1

to

[General]Version=2

Save and close the file.

Force a replication of the GPO by opening a command session and typing

secedit /refreshpolicy machine_policy /enforce
