We are using Websphere developer studio or DB2 CONNECT to connect to database which is on UNIX/AIX server from windows system through two diff IDs.(Say A and b).with A whenever we try to connect connection gets established faster,but when we trying using B ID the connectivity establishes in long time, sometimes even 3-4 minutes.
If other users try to connect to database db2 thru B they get connected fine sometimes and sometimes even for them it takes time,i mean this problem is intermittent.
what might be the cause.

Also B has more priveleges than A.
