Errors with installation of 4.6b

After installing 4.6b, I started the MMC and the SAP R/3 server by right-clicking. The color of the icon changed to red. I checked the syslog viewer, and it showed the errors:

R/3 Basis System: Initialization DB-Connect Failed, Return Code 000256 R/3 Basis System: Operating system call...

connect failed (error no. 10061) R/3 Basis System: Failed to establish a connection to the message server Please advise.

This could be due to several reasons.
Here are some things to check:
-services file (under %systemroot%system32driversetc) needs to have the sapdpxx and sapmsXXX entries
-the &gtsid&ltadm and SAPService&gtSID< Windows accounts need to have login permissions to the database server
-the system profiles need to be present and configured correctly (check under usrsap&gtSID&ltsysprofile)
-the R/3 kernel should be current
-the MMC needs to be registered correctly
