wouldn't that then restrict the use of the link to people in that group? at the moment we have a service account using it too which works fine.
Yes, it would. So you would have to add a separate linkedserverlogin for that service account, specifying that it uses its own credentials. This would be a pain if you have a lot of such accounts.
I seem to remember an option to specity the security for "all other accounts" (ie what to do with accounts for which you haven't specified what credentials to use at the remote server, but I can't find any documentation for it in BoL, and I don't have a 2005 installation that I can play with to see if it shows up in SSMS. If that option does exist it would make things simpler.
