check in replication monitor and restart the agent, if not resolve then run trace on server and find cause for it.

No need to restart the server, just check is there any blocking in server.

where did you configured Distributor,is at 2005 or 2000 server.

from the above mentioned publisher,which version of 2005 are you using. is it Dev or Enterprise.

which Distributor are you configured,is it 2005 or 2008 and check the distributor end.

we can use Attach&Detach methods

There is no DBCC Log command...in ss2k5

u can do the restoration tasks with particular extensions and should check the file location where u have to restore

Regard to your question,give the exact context that publisher server is failed or distributor or subscriber.

depend on particular failure of server,i can post my solutions
