My service provider has given me access to their SQL server through a VPN connection.

Here's the problem:
Sometimes i can't get owner rights to the database and sometimes i can. What happens is i can right click on a table in enterprise manager and get design view sometimes and not other times. Usually when the server experiences a load i think i have problems. but not too sure.

what is the poll interval and what packet size and what login timeout shall i have?

Thanks in advance.
