  • It sounds like you've already peformed a previous installation of LCS/OCS into that SQL instance.  IF so, you'll either need to manually delete the databases on the SQL backend, or if that SQL server is hosting another in-use OCS FE then you'll have to install a second SQL instance to support an additional pool.

  • Yes Jeff you're right.

  • In that case I would recommend removing the entire SQL instance and reinstalling a fresh one, just to be on the safe side.

    You can follow these directions for SQL Server 2005:

  • Can you clarify what you are using that SQL instance for, it's not very clear.

    If it already has other non-OCS-relted production data in it, then certain don't remove the instance.  I would not recommend sharing a SQL instance between OCS and other applications so in that case it would be best to install a new, separate SQL instance to be used with only the new OCS installation.

    Then, if you haven't already done so, you can manually delete just the RTC databases from the original instance to clean up the data but not affect other DBs in that same instance used by other unrelated products/applications.

  • you can also create a new instance and then install the OCS. Have u tried that ?

    I also get through this error, then I delete all the entries in db ,also deleted all the entries in DNS and AD too(just for my satisfaction).

  • As i said earlier i would rather prefer to install OCS in existing SQL server not in different instance

  • Take a look at this article and see if you need to clean up any references to the back-end DB within AD:

    I'd again suggest you use a new SQL instance (on teh same box) as sharing the OCS databases with other DBs is not really a recommened best-practice.  Having additional SQL instances on the same server is quite simple, it's not like you need to deploy a separate server in case that is what you think we are inferring.
