OK, I am not feeling the love here with Horizon View 5.2. 
I got the View components setup and finally got to create a "Pool" and I get this error when creating a Pool...
"View Composer Database Fault: VMware.Sim.Fault.Db.Operation.Failed.Fault"
Not cool. The KB1035727 found on: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1035727
didn't help. I even deleted and re-created the local system DSN, no bueno!
I even granted the credentails that all the services run on with "Domain Admin" rights, still get the error. I thought that *maybe* the account didn't have rights to create accounts in AD, but still get the error. Being Domain Admin means it had local admin rights but I added the creds into the "Locak pages in memory" and "Log on as service" and manually added the creds in the local administrator group. No luck!
I granted the SQL account that the Viewcomposer uses, still get the error. I though the account needed more rights, still error.
All the servers in the View lab can ping, nslookup and telnet (to the esxi hosts port 902) to each other fine. No DNS issue that I was able to find.
Frustrated now.
Any ideas?
Right now I am blowing away all the machines involved in my Horizon View LAB and going to rebuild.
Thanks
