I am cleaning up an Active Directory Domain for someone.  One of their complaints centers around the fact that when the domain controllers on the Forest\Domain (it is a flat design) are rebooted they take an extremely long period of time to boot up and replicate with each other.  GPO processing is especially acute.

I noticed they applied the GPO setting 'Always wait for the Network at computer startup and logon' in the Domain Controllers Policy.  I have never applied this at the DC level.  It seems this would be the cause of the issue but I would like to get a second opinion before I disable it?

Thanks

I wouldn't recommend using this setting on a DC. Servers usually do take longer to boot than a normal PC but requiring it to wait for a network connection just makes the process longer, especially if there are processes/programs with a higher priority than your network services on the server.

This settings will ensure that logon is not possible until startup policies are applied.  Usually this is not enabled and thus policies run asynchronously,

What OS is the server and what functionality is the domain? It could also be waiting for DNS to get loaded from Active Directory if it is integrated.

The OS w2k8 R2 SP1.  The functionality is Windows 2008 R2 at Forest and domain, with ADDNS.  I think that is exactly what is happening, waiting for DNS. Sounds like I need to disable that GPO

Disabling the GPO resolved the problem
