What can also cause it is if the zone name in DNS is cbs2kdom1.edu or cbs2kdom1.local, but the Primary DNS suffix is cbs2kdom1, it won't work. The resolver/registration service uses the Primary DNS suffix to register into. If the zone name that matches the Primary DNS Suffix doesn't exist, then tehre's nothing to register into.
What is the AD DNS Domain Name? If you look in ADUC, it will tell you the AD DNS domain name. Is it cbs2kdom1, cbs2kdom1.edu, or cbs2kdom1.local?
Which then makes me ask, why do you have those additional Search Suffixes set?
If the AD DNS domain name and zone name are both cbs2kdom1.local or cbs2kdom1.edu, then you have a Disjointed Namespace. It doesn;t match the Primary DNS Suffix.
If the AD DNS domain name is truly cbs2kdom1, then it's a single label domain name issue.
This can also cause it. Single label names are extremely problematic. Apparently that was erroneously chosen during domain creation. Your Primary DNS Suffix is "cbs2kdom1" which is not a valid DNS zone name format. DNS is hierarchal with at least two levels, such as cbs2kdom1.com, cbs2kdom1.local, etc. After Windows 2000 SP4, Microsoft put a damper on single label names with resolving capabilities as well as with DNS registration. It's even tighter with XP SP3 and newer operating systems.
Why was this done you may ask? Good question. During resolution, DNS will actually look at the root hints before it even looks at it's own zones, which caused excessive internet DNS traffic to the root hints. ISC found it and complained, whereas Microsoft made the necessary changes to accomodate. Read my blog on it for a further explanation. There is a "bandaid" for it, but that's all it is and it must be applied to ALL machines until you get a chance to perform a rename or migrate to a new forest/domain with a properly formatted name.
