Here is the problem.

One NT 4.0 SP6a Server installed as BDC runs Exchange servers. Daily backups are performed from this server using ArcServe. The following things are backed up:

1. This server completely including all drives, Exchange and registry.
2. PDC and another BDC completely including drives and registry.
3. Member server from other domain completely (drives and registry).

The problem is that registry from PDC and another BDC are NOT backed up with error
DRIVE=\\servername\admin$ - no such logon session
But local registry and registry from member server are backed up OK.

Can't get what's wrong.
Any ideas are greatly appretiated.

I've run into similar problems, but not this one. One thing that sometimes works is to map the target shares on the remote machines on the local host. Make the mapping persistent so that a connection is always made at startup. I don't know why this works sometimes, but it has, so I left it alone when effective. If it doesn't work, remove the mapping and carry on - somewhere there's got to be an answer. This should be easy to do!

Sorry, mapping admin$ share both manualy and from pre batch did not help. Still the same error. Thanx for your time.

Hi, their are several ways to Backup a remote Registry, but the best one:
U can define a Start before and after Batch in the Job definition of Arcserve. Go to it an add the Command "rdisk -s", with this the Local Registry is saved under C:\winnt\Repair. In some Cases, like you have the big big Problem with blue... then it's goot to have an second Installation of NT on the machine. You start that and use the Expand command to extract the registry files. From system._ you get System, then copythat files to the right folder (Winnt\system32\config).

Another Way is to install an Ofant (Open File Agent for NT) for the DC's of you're domain. But this doesn't works if you have the single Server Version of Arcserve, normaly you had to takethe Enterprise Version of it to backup remote Server.

Thanx for your time but there's no way rdisk will help in my case. And changing the configuration of server (i.e. adding another installation of NT) is not an option. And as I described in question ArcServe can successfully backup registry on memberserver from another domain - so version is not a problem (BTW - everything works great on another site).

Hi,
give me the second chance. Arcserve is reporting that the Admin$ share is not existing, but i mean that arcserve needs that share to backup the registry. Look if the share exists.

Hi i recveid youre mail,
the admin$ share exist. Look if the Root share C$ exist too and try to connect to it from the server with Arcserve.
Many Problems are issued from Password changes, since the passwords for the services accounts not changedautomticaly.
Have look on the Service account for Arcserve and check if it's correct.
If the password is changed (try stop and start the Service) such things could happen. You could backup some Server and others particulary not, depending on thecache for SMBs.

I will look if i have some other hints for you, but the anwser must very simple for your Problem.

To Frobo:
Yes, this share exists and I even can connect to it manualy. Any other ideas?

by vagab0nd

To Frodo: You're right, I've changed the password recently, but I did change service account password in ArcServe Server Manager, the same as for backup agent for exchange and all other places. I restarted all ArcServe services after this. What's more - I can browse registry on all servers through ArcServe manager - so I do have permissions.

I now it should be easy but I can't get it myself. Any other ideas?

Remote Registry Backup Operation

The Registry files on remote NT/2000 workstations/professionals and servers are automatically backed up when the corresponding default check box for "Back Up Registry" is on for either foreground or background operation. The operation is similar to the registry backup on a local system. The registry is always backed up to the first set that is processed to storage media. Note that a multiple set backup can be defined to process logical disk volumes to storagemedia in any preferred order. (E.g. "C", "D", "E" or "D", "C", "E".)

Registry Tool is a centralized Windows registry editor and registry utility capable of remote registry administration, maintainance, analysis, compare, and recovery / restore operations on the Windows 95 registry, Windows 98 registry, Windows ME registry, Windows NT 4.0 registry, Windows 2000 registry, and Windows XP registry. Registry Tool also tracks system and driver files by version and all other relevant file properties.
