How to give permission to sql server services?

[esthrim]

Hi All,
i have a problem with my sql server when trying to execute this command

exec xp_cmdshell 'dir \\nvs\data'

it will result "access denied" message. (nvs is a novell netware server)

But if i run this comand from command prompt. it worked.

Can somebody please explain how to add permission to sql server for accesing novell shared folder??


Thanks Alot(sorry for my bad english)
