Replication and GP issues

Hi,

Problems facing:
1. Replication not working from DC to ADCs
2. Group policies are not applying on client machines or on ADC. But successfully applying on DC.
3. \\Domain\sysvol\domain path is not accessible from clients or from ADC. But can be accessible from DC.

Background Info:
Recently upgraded our DC from 2000 to 2003. After upgrading to 2003, configured ADC, but it is not fully replicated with DC (SYSVOL and NETLOGIN are not automatically shared in ADC after DCPROMO). Situation is same till now.
So due to this above scenario, I dont have the option to transfer/seize roles from old DC as I dont have fully functioning DC.
IMP: DC was upgraded 2 months back and Group policies were working till 15th JAN. Ofcource replication from DC to ADC never worked.
I suspect at two points..One is with DNS, becaues ForestDNSzones and DomainDnsZones are not appearing in DNS after 15th.
Second is with Security database, bacause event IDs 1925, 1126 and 1104 are frequently coming in DC.

Things done till now under troubleshooting:
1. Reset machine account password
2. checked SMB siging related issues. (No issues)
3. DNS completely reconfigured.(DomainDnszones and ForestDnsZones still not appearing in DNS console. But they are present in CN=partitons. Checked with ADSIedit.
4. Checked for SYSVOL permissions and found no issues.
To remind you again GPO are applying on DC but not on ADC and other client machines.
5. Reconfigured secedit.sdb

Events frequently getting:
On Domain Controller:
4000,4013,1925,1126,1104,40960,1053
On ADC and on other clients:
1030 and 1058

I appreciate your help in this regard.

Thanks,
Raju P.

It seems more likely to be the DNS configuration problem. Check srv records
