Hi Riko123,
I had the same problem, but no solution on the Net (note that I found a report on the same problem from back 2003!).
My ARCserve is v11.0, and is running on a HP Proliant with Windows2000. The original installation was OK, but after reinstalled it, SNMP got corrupted.
Then I took a look what is happening when SNMP starts. The immediate breakdown of the service is due to a mis-spelled path, that the service tries to open: 'C:\WINNT\system32\"C:\Program Files\CA\BrightStor ARCserve Backup\CSTool.dll'
Very funny!
Then I browsed through the registry, but could not find a particular place where I could make a correction for the path - I don't know where it comes from...
The good thing is that SNMP tries to open this dll from each and every locations in %PATH%, including C:\WINNT, and C:\WINNT\system32.
I tried adding C:\Program Files\CA\BrightStor ARCserve Backup to the %PATH%, but no success.
Then I copied CSTool.dll to C:\WINNT, and finally it works.
Note that I did not check if SNMP is completely operational in ARCserve, but anyway it seems to be OK!
Please tell me about your findings!
Cheers
Zsolt
