network installation of Primavera P5

Hi all, i am newbie to the site and work actually in the IT dept as IT administrator.
we just bought the new version of Primavera P5. i am trying to do the installation and it wouldnt connect to the database.(i have absolutly no idea on neither working with Primavera nor installing it previously in a network)

i will give a brief about the systems
Server :
hardware - HP dl380 G4
software -windows 2003 enterprise edition with sp2 installed.
database - Microsoft sql server 2005 with service pack 1 installed.

client:
hardware - lenova M55 model
software - windows xp with service pack 2 + uptodate patches installed

the error i was getting is after the client installation, while i am trying to connect the database, it couldnt connect to either PMDB or MMDB and it gives an error as Bad Privuser or password , check the group id(i tried connecting with privuser /privuser and pubuser/pubuser id’s ) and the error is consistent accross the user id’s. but from the same client i can connect to the PMDB / MMDB using the above privuser/privuser and pubuser/pubuser id’s through ODBC32 connectivity.
any help in this regard would be much appreciated.

thanks in advance for everybody’s time.

regards
SK.
