A few questions to clarify your issue:
I  suppose you're saying that they're unable to access resources in their respective site's local LAN?
By "cannot access"- do you mean that they cannot be authenticated by the local server (access denied messages while you're still able to ping the server by name) or are you not able to resolve at all? Not even using the resource's fully qualified name?
Are the remote sites "real" secondary sites or are you using an Active Directory integrated DNS zone? Just tell me you're reasoning so I understand any limitations you might have due to policy or something
what happens if you use nslookup at the remote site - who is the autharitative server they come back with?
Just a quick win: are the DNS servers set up in correct order in your DHC scope (local first)

loads of questions, but it makes troubleshooting a lot easier if more info is known :-)

Hi ThaMbu.

Please make sure each of the DCs in sites B, C and D are set to be Global Catalogs.  You can do this through AD Sites and Services.

This will correct your login issue.

Dear sven_jambor

It will take more time to login

If i open my computer,the sytem will hang(I have mapped network drive which is mapped by login script).If i remove the network cable,it became fast.If i click on share drive it will give me access denied messages

If i restart the local Dc, evrything will fine even before my wan connection back
DNS server order is correct

Okay, that makes sense. Just to be sure: are the local DCs Global Catalog servers?
