Netlogon got the following error while trying to get the subnet to site mapping information from the DS: A device attached to the system is not functioning.

we have two servers in domain one is Win 2008 R2 as domain controller and other is Win 2003 Backup domain controller with exchange server 2003 installed over there. Both severs was expecting error of active directory replication tombstone lifetime error 2042 which has been recovered after changing the registry key "Allow Replication With Divergent and Corrupt Partner" to 1 and after rebooting both servers the netlogon service failed to start on win 2008 R2 server.

What is the error for the netlogon, is it related to a journal error? D2/d4 bug track is the fix. The error should include how to fix it.  Make sure you see which is authoritative.  Disable ntfrs replication when running the repair.  Also make sure to backup the c:\windows\system32\sysvol files.
Net share will show you where sysvol is and you can look within to see if you have a prestage/preexisting from which you could copy the files out if those are the correct ones

Make sure there is a sysvol and a sysvol\netlogon folder.  If the netlogon is missing, it can not be shared .....

This issue comes up if the replication once fixed triggered based on the wrong source as the master, I.e. 2003 had outdated empty data and it was seen as the reference server when replication resume clearing the contents of the win2k8.

There is no share folder SYSVOL and NETLOGON found on windows 2008 domain controller. where as some other errors occurred in event log related to active directory replication.

1. The DFS Namespace service could not initialize the trusted domain information on this domain controller, but it will periodically retry the operation. Event ID 14548 "
2.  Active Directory Domain Services was unable to establish a connection with the global catalog. event id 1126
3. The processing of Group Policy failed. Windows could not determine if the user and computer accounts are in the same forest. Ensure the user domain name matches the name of a trusted domain that resides in the same forest as the computer account. event id 1110

besides the above errors main issue is how can we start netlogon service at this stage.

c:\windows\sysvol

The issue is likely depending on which server can up first and was the basis of the replication.

Do you have a preexisting folder there?
windows 2003 <=> Windows 2008 R2 will replicate using NTFRS using the fileshare windows 2003 services.
Your error suggests it is using DFS-R for replication........
If you relocated the sysvol c:\windows\sysvol to DFS-R, The naming suggested for such is c:\windows\sysvol_dfsr but I do not know which guide the person who performed this task chose, so finding the domain scripts policies folder names is the only way to locate the folder that would be shared as sysvol and netlogon.
