you don't have to disable the default domain policy, and that is not recommended anyways. you can just creat whatever policy you like, and link it anywhere you like.
paste the event id 1000 description so i can know about the cause. another tool you can use is RSop or gpresult.exe. run "gpresult.exe /v" and check what policy has been applied, what settings have been made.
if you can't get a clue from event 1000, you may want to enable userenv debugging log, per http://support.microsoft.com/default.aspx?scid=kb;EN-US;221833.
then search any thing you think is valueable in microsoft KB.
Again, all these suggestion can serve as just a start point. there are too many things can cause GP application error, including DNS, connectivity, permission, FRS, DFS, AD replication, you name it.
