Create Multi-server environment in the SQL 2005- need HELP

I tried to setup a master-target server for the multi-server
environment
I tried the step in the microsoft support page already, but I keep
getting stucked with Create master wizard's third and fourth step.
This is my scenario: I have computer A and B connected in my network.
All of the SQLServer and SQL Agent in both machines uses a windows
authentications.
Both machines can communicate well already.
So, in the Create Master Server Wizard at Computer A I do:
-> Next
-> Next (leave all values blank for the email, pager and net send
address)
-> Add Connection to Computer B with windows authentication
-> Check compatibility success (meaning that the login successful as
well), then close
-> I check the "create a new login if necessary and assign it rights to
the MSX", then next
-> Finish
In the 3rd step: "Ensure the agent startup account for 'Computer B' has
rights to login as a target server", I got this error message:

Need help deperately >,<Are your servers domain members?
It looks like you have a problem with login from one server to other.
Accordint to the error messge '.\TargetAdmin' is a local account.
