When and why do i have to use a Network-Path?

Hello,

i'm wondering when i why i have to use a Network-Path in KM.

I'm able to connect to a File-System Repository, even if i have no Network-Path defined.

- both run on W2K Server

- EP runs on host EP (not an Domain-member)

- Filesystem is provided by host FS (Domain-member)

- EP is started with the default local-user SAPServiceEP6

- on the FS host, i have defined also a local-user SAPServiceEP6 (because EP always wants to logon with these credentials, i have checked this in the windows securitylog of host FS)

- no network-path defined

So regarding the fact, that everything is working, can anybody tell me when i have to use a Network-Path?

Thanks in advance

Frank
