collation & compatibility issues

1) how to check the colllation settings on SQL 7 ?
2) I have 2 SQL Srv - SQL7 and SQL2000.
A client application does the following:
- retrieves data from SQL2000 to the SQL7 for queries.
- data updated in SQL7 is also periodically syn with the SQL2000 srv.
there is no direct user acess with the tables, all is interfaced thru the
client app. So must the SQL Server 2000 compatibility settings (under server
properties) be changed to 7.0 ?
Problem is there is frequent blocking on SQL2000 by SQL7, preventing the
SQL2000 from being accessed by other app.
The WAIT TYPE is usually networkIO for the blocking connection from SQL7 to
SQL2000.
So I suspect could it be collation settings or some other in-compatibility
between the 2 SQL Servers.

The error log will tell you this information.

You should run a blocker script to identify the top of blocking chains. The
script from this article might help:
