[ms-sql 2000] linked-servers and low privilege service account.

[elite_netbios () yahoo com]

Hi,
While hardening ms-sql 2000 for a DMZ installation, I faced
with a problem, stopping me at serious point.

While using a normal user account for running SqlService , seems it's not
possible to use defined linked servers (linking to Oracle in this case )
because
of limited privileges. After few try and errors I noticed that only
members of "Local Administrators"
are allowed to use defined linked servers , meaning 'SqlService' account
should be
SYSTEM or a member of admin group , which is not a good idea.
currently I'm using 'OLE provider for Oracle' . I tried ODBC link but
seems this solution requires
user to be privileged too.

How can I permit my defined low-privileged user account to work properly
in such scenario ?

regards
Hamid
