Problem With Xp_cmdshell ,BCP And Network Drives

Basically what I am trying to do is run bcp from within a stored procedure in SQL 6.5.
It allows me to dynamically assign the destination filename (the legacy application expects to see a file for each picking slip) I want to store the file on another server/shared directory on the LAN

Here is the code
DECLARE @ship_no varchar(16)
SELECT @ship_no = '1234567'
DECLARE @SQL_SYNT varchar(255)
SELECT @SQL_SYNT = "master.dbo.xp_cmdshell " + '"BCP AUSTCHAR..armaster out servernameBECpsqlout'+@ship_no+'.cba /c /t , /r
/Sservername /Uuser /Ppassword"'
EXEC( @SQL_SYNT)

However I get the following output:

(1 row(s) affected)


(1 row(s) affected)

output
---------------------------------------------------------------------------------------------------------------------------------------------
DB-LIBRARY error:
Bcp: Unable to open host data-file.

The destination file is not created.
I have tried:
making the path the local HDD that works:
Using a mapped drive, that does not work
Running the same bcp command from the command line. That works.
Using UNC's (as above) You can see the result.
I have also checked security and made SQLexecutive ran as the domain admin. Did not work.


Can Anyone help?

Thanking you in advance
