Cannot start Microsoft SQL Server agent & Enterprise manager

Hi:
I am receiving the following error message while trying to open Enterprise
Manager in MSSQL 2000 Server.
---
A connection could not be established to ABCD
Reason : I/O error 1117(the request could not performed because of an I/O
device error.) detected during read at offset 0x00000000b1e000 in file
'Drive:\Microsoft SQL Server\MSSQL\data\master.mdf'..
Please verify SQL Server is running and check your SQL Server registration
properties (by right cliking on the ABCD node) and try again.
---
This is a Windows 2000 server (Service Pack 4) + MSSQL 2000 (service Pack
3). The MSSQL server service SQL Server Agent services are running under
local system. This is a Standalone machine.
Help is required on an urgent basis as this is a production server.
With Regards
MitulYou have a problem with the mdf file for your master database file. Possibly the file is locked by
some other process (like anti-virus). If that is the case, try again. If you are unlucky, the master
mdf file is corrupt for some reason, and you have to go the rebuildm.exe route.
