Primary DC schema Owner is deleted

I'm running a Windows 2003 PDC and I'm getting random netlogon event ID 5719 errors. I've run dcdiag and received the following:

I'm at a loss as to why this would just appear for no apparent reason. I've retraced my steps and have found NO significant changes that have been made since this error began appearing in event viewer.

Did you have a domain controller that you deleted or did a metadata cleanup on?  Anything like that happen recently?

What does it show if you run

netdom query fsmo

Thanks

I immediately got an RPC server unavailable error which leads me straight to DNS.

DNS or port blockages would be the first things I'd investigate

I'm pretty sure now that it's a DNS issue. The random RPC error and an occasional user over the last day or so saying that their client could not connect to the domain have reinforced this. The only thing I'm a little concerned with is why this would relate the the PDC schema owner being deleted.

So the problem seems to be fixed as of now. It was related to the scope options in my DHCP server. For some reason, it was no passing DNS or Gateway addresses. I removed all settings and reconfigured the scope options and we are back to normal. No more event viewer error 5719 and client's are not randomly throwing out errors about no connectivity to the domain. Now I just need to figure out what caused the scope options to go rogue. For now I'm calling this "fixed" and moving on. Thanks for the suggestions.
