RMAN restore problems

Question

Hello,
I have an 11.2.0.1 database (archive mode) on a windows server 2003 R2 32b. The database does backups via RMAN (catalog on other server for that purpose) with NMO (legato networker) and it work fine. But we can't restore the backups. It may be a problem with the database, but it seems more a Media Manager problem. The fact is that when we try to restore, RMAn hungs waiting for recover (without any error, just stays forever until killed), and a session on our backup server remains browsing. It happens also if we make a restore validate. On the other hand, if you make a crosscheck, it works fine.
As I said, it's very strange, and I think it's an issue with the configuration of the networker, or even the server, but I post here looking for advice, or maybe someone has seen something like this before.
Any advice would be apreciate, since the only option we have now, it's to reinstall the whole server (OS and database) from a cold backup (copy of datafile,ctrl,...)
Thanks

By the way, we've made some tests:
- backup and restore with diferent versions of networker client and NMO (thought they were on latest release). Same result.
- We've created a new instance on that server, blank, and registered new in the catalog. Same, backups, but cannot restore. With this, we've discarted the database issue...

Hi,
yes, the problem was in the comunication between the Media Manager and the client. On the way to the MM, it was all ok, but in the opposite way, MM looked just for 'server' and couldn't find it. Adding the alias on the /etc/host, MM could find the 'server' as it has then 'server.domain'
As for the scrip, I'll post here the script used for duplicating the prod database on a new installed desa machine. Solved the comunication issue, it worked more than fine.
run
set until time "to_date('Mar 20 2011 23:30:00','Mon DD YYYY HH24:MI:SS')";
allocate channel ch1 type 'SBT_TAPE' parms 'ENV=(NSR_SERVER=bckservr.privada,NSR_CLIENT=origsrvr.privada, NSR_DATA_VOLUME_POOL=poolBCK)';
allocate auxiliary channel ch2 type 'SBT_TAPE' parms 'ENV=(NSR_SERVER=bckservr.privada, NSR_CLIENT=origsrvr.privada, NSR_DATA_VOLUME_POOL=poolBCK)';
DUPLICATE TARGET DATABASE TO DBSIDDES;
With this script we duplicated de database with SID DBSIDPRO in the server origsrvr, to the server destsrvr with SID DBSIDDES. We used a set until time, so we take the last cold backup make this weekend.
