Problem on Saving Data to one of the Database but work normal on other DB

Hi All,
I have some trouble on supporting a Windows Base System wrote by DELPHI
language implemented in my Company
Environment :
There are two Windows Server 2003 Std Ed servers
Server1 is Application Server
Server2 is Database Server(MS SQL2000 Std SP3a)
Hardware:
IBM Dual Xeon CPU
4GB Memory
Raid5 with 137GB Harddisk Space
Networking:
Server1 exposed to the Internet with firewall protected
A cross over cable connected between Server1 and Server2
Our Case:
We setup the Application on Server1
And all Workstations using the Windows Base Interface to use the program
If some user work outside Office, they will use the program through a remote
connection named TAXXI(http://www.taxxi.com).
Now we met a problem, on the SQL Server, we have created 3-5 database for
different group of users.
One of the database named D on the SQL Server always hang without any error
log.
It suddenly hang when user save their Data.
They can get the data from the System ,
only Save the data will make the screen freeze and lost of data after the
system back to normal in a hrs later.
We can't find any strange log on the EVENT VIEWER or SQL Server Log
From the Performance Monitor, we just found the Page Fault/sec was high and
always reach the Peak on Server1.
For Server2, only Write to Physical Disk was high.
If we login to other database in the time database D freeze the user screen
when save,
it works normally with input or save data to the system.
Plz help and give some suggestions for us to solve the problem.
Thx
JackHave you checked for database blocking during the save operation?

up, use sp_who or Sp_who2, and check the blocking field. If it is non-zero,
then the corresponding spid is being blocked by the spid in the blocking
field...
This problem is generally caused by long-running trasnactions.
