Detail your installation!
Are wanting to do the following:-
Install Access
Place an Access Database on the server
Publish that Database
If so, you need to see about getting help from a consultant as for a complete novice to Citrx, and working with a production server, I certainly wouldn't recommend it.
If Access is already installed, the you could copy the database and publish it as follows:-
Using Citrix Management Console:-
"C:\Program Files\Microsoft Office\Office\MSAccess.Exe" "D:\My Database\Database.mdw"
Then select a server, group of users. Then right click the new application and Load Balance it, I'd suggest User Load for the time being.
Or wait until your Citrix geezer returns!
Cheers,
Carl.
