DB connect problem,Disp+Work.exe dies and the work processes die on startup

Question

Dear Experts,
I am getting the error on SAP startup,Disp+Work.exe dies and the work processes die on startup.
I found below error in my DEV_W0 trace as below
*failed to establish conn to np:(local).*
*C  Retrying without protocol specifier: (local)*
*C  Provider SQLNCLI could not be initialized. See note #734034 for more information.*
*C  Using provider SQLOLEDB instead.*
*C  ExecuteAndFlush return code: 0x80040e14 Stmt: [if user_name() != 'pec' setuser 'pec']*
*C  sloledb.cpp [ExecuteAndFlush,line 5989]: Error/Message: (err 4604, sev 0), There is no such user or group 'pec'.*
*C  Procname: [ExecuteAndFlush - no proc]*
But i could see the user 'pec' is availble in my database users list  with db_owner , public permissions also been assigned to it.
However When trying to delete a user on SQL server 2000, we recieve the message "You cannot drop the selected login ID because that login ID owns objects in one or more databases.".
Please refer the below work process trace and please suggest the possible solution..

Hi Rohit and Subhadip,
My problem was solved, thanks for your effort.
reason is that, user 'pec' not been associated with login user for the SQL server.
subha : when i execute the first command which you suggested, but couldn't find any user's list.
so i didn't  tried with the second command. just to give a final try i have executed the script like below and its worked out.
USE PEC
GO
EXEC sp_change_users_login 'update_one','pec','pec'
GO
Now i see that all work process are starting,,,thank you so much rohit and subhadip
I could have try this first ,when you guys suggested since i couldn't find any output with the first command i didn't proceed with second one.
Since deleting and creating method doesn't seems to be a good, i have just to give a try executed the second command and its worked.
Thanks for your time and patience
Many Thanks,
Vinod
