PDC can't find Domain?

Did you add the servername to DNS?

Verify your Wins server, if you had an old entry for the previous PDC, you must change the record to point to the new one.

The first thing I would do is check all of my TCP/IP settings (IP Addressing, subnet, DNS, etc), I would verify that the name of the domain was entered correctly during installation. Have you tried pinging any other nodes?

When you reinstalled did you give the same name? If you did then the new SID will conflict with the old SID (Security Identifier). Demote to BDC rename and then promote to PDC.
Did you promte another BDC to PDC while you did reinstall? If so you must demote that one before you promte your new PDC.
Hope this helps

Two important issues are your browser service and the LMHOST file.

To resolve this issue, modify the Lmhosts file that contains the 1b and 1c entries for the PDC of the trusted domain:

In a text editor (such as Notepad), open the Lmhosts filelocated in the %SystemRoot%\System32\drivers\etc folder.

Add the following lines to the Lmhosts file, using the name of the trusted domain, the Internet Protocol (IP) address, and the NetBIOS name of the PDC in the trusted domain, as indicatedin the following example:

10.0.0.1 PDCName #PRE #DOM:DomainName
10.0.0.1 "DOMAINNAME \0x1b" #PRE

Replace 10.0.0.1 in the example with the IP address of the PDC in the trusted domain.

Replace the PDCName with the NetBIOS name of the trusted domain PDC. When you specify the NetBIOS suffix (the sixteenth character), the spacing between the quotation marks is critical. There must be a total of 20 characters within the quotation marks (the domain name plus the appropriate number of spaces to pad up to 15 characters plus the backslash (\) plus the NetBIOS hex representation of the service type).

Replace DomainName with the Windows NT 4.0 domain name of the trusted domain.

Save the changes to the Lmhosts file.

Specify the use of the Lmhosts file:

In Control Panel, double-click Network .

Click the Protocols tab.

In the Network Protocols box, click TCP/IP Protocol , and then click Properties .

In the WINS Address tab, click the Enable LMHOSTS Lookup check box, and then click OK .

Click Yes when you are prompted to restart your computer.

MORE INFORMATION
This behavior can also occur if you manually added the RestrictAnonymous registry value to the registry on the PDC of the trusted domain. This value prevents null session connections. In addition, this registry value also prevents a trusting domain from connecting to th

Recommended is to have a BDC before reinstall PDC which you will promote as PDC \save data from old PDC(actually BDC)\reinstall as BDC (with partitions as you wish)\recover data\Promote as PDC.(use a backup application capable to restore the permissions for saved data)
