RU1 upgrade worked! It seems that NTLMv2 isn't supported after all at RU1 upgrade at least, older versions are denied by Group Policy in our domain. It is funny, that SQL Windows Authentication worked until RU1 update with 12.1.
I don't know if it was Tom Petty and Free Fallin' that made the upgrade finally work, or pete_4u2002's advice. Both happening at the same time.. well you can guess.
The starting situation: At this point I had already ran once RU1 and failed on SEPM1 server. The SEPM1 has 12.1 RU1 files but DB has old 12.1 schema. SEPM2 is running 12.1 files and SQL has 12.1 schema.
We changed SQL Server to mixed mode.
Stopped SEPM Service on both SEPM Servers.
Started Management Server Configuration Wizard on the previously failed SEPM1 server:
- Reconfigure Management Server
- Accepted other defaults which were given at the original installation
- Changed Authentication Type from Windows Authentication to SQL authentication
- Gave new Database user name (SQL account) and password
- Wizard noticed that the schema is too old, and started the RU1 upgrade wizard (!)
- Wizard completed succesfully
- Tested SEPM1 UI succesfully
- OK!
Started Management Server Configuration Wizard on the previously working SEPM2 server:
- Reconfigure Management Server
- Accepted other defaults which were given at the original installation
- Changed Authentication Type from Windows Authentication to SQL authentication
- Gave new Database user name (SQL account) and password
- Wizard noticed that the schema is too NEW, and FAILED
That was kinda expected, must run upgrade wizard now, which is expected to fail due to DB problems:
- Next
- Setup.exe Upgrade wizard complained about pending reboots.
- Changed Symantec Endpoint Manager service to manual and rebooted.
- After reboot, changed Symantec Endpoint Manager service to automatic
- Started setup.exe
- Failed to the DB Wizard (obviously, since DB account is using Windows authentication - must change that)
Started Management Server Configuration Wizard again on SEPM2 server:
- Reconfigure Management Server
- Accepted other defaults which were given at the original installation
- Changed Authentication Type from Windows Authentication to SQL authentication
- Gave new Database user name (SQL account) and password
- (No need for DB wizard again)
- Tested SEPM2 UI succesfully
- OK!
Created new 64 bit client packages and updated server clients. Done! Thanks to everyone for help, especially pete_4u2002!
I Won't Back Down ;-)
