Unable To Access VM Network Drive In SQL During Backup Generated By Stored Procedure

I get the following error in a log file created in the osql command:

Msg 3201, Level 16, State 1, Server KAC2KGS2, Procedure usp_Kaman_Full_SqlDB_Backup, Line 150
Cannot open backup device 'x:Servername_master_sqlbu_200703101930.bkf'.
Device error or device off-line. See the SQL Server error log for more
details.
Msg 3013, Level 16, State 1, Server KAC2KGS2, Procedure usp_Kaman_Full_SqlDB_Backup, Line 150
BACKUP DATABASE is terminating abnormally.


The device is established in a CMD file right before the osql command is started that starts my stored procedure. The CMD in this file is:

for /f "tokens=15 delims=." %%i in ('ipconfig^|find "IP Address"^|find "192.168"') do set SUBNET=%%i

:loop
if exist x: net use x: /del
net use x: \192.168.%SUBNET%.1ackup
if not ERRORLEVEL 1 (
goto continue
) else (
echo FAILED TO CONNECT TO BACKUP SERVER >> "%SystemDrive%LogFiles\%Computername%.log"
sleep 60
goto loop
)


:continue

echo IP ADDRESS OBTAINED

Echo delete old log file if it exists

if exist %3\%computername%_kaman_full_sqldb_backup_old.log del /Q %3\%computername%_kaman_full_sqldb_backup_old.log


Echo Rename log file to old.log

rename %3\%computername%_kaman_full_sqldb_backup.log %computername%_kaman_full_sqldb_backup_old.log


echo backup SQL Databases on server will start now

osql -E -n -d %1 -i %2kaman_full_sqldb_backup.sql -h-1 -o %3\%Computername%_kaman_full_sqldb_backup.log


In the stored procedure I try to use the x: drive and that does not work. I have tried obtaining the \192.168.x.x address and that only works on some of my servers. All are running SQL 2000, some are using Win2K and Win2003. It does not seem to matter. One of them that is using Win2003 only fails occationally.

I notice when I do a

exec master..xp_cmdshell 'x:'

The system cannot find the drive specified.

Yet, when I go to the server there is an x drive.

I am using the sqlserv user to run the job and that use is an administrator on the local machine. This is a virtual machine. We add the X before the osql and drop it after the command finishes.

Any help would be appreciated. Thanks, dbmsql
