RE: IFS security? -- MIDRANGE-L

Tony,

Basically, think of QNTC as "Network Neighborhood" for the iSeries.
Typically, the system will discover the NT based systems (NT, W2K, XP) on
your local network and list them under the QNTC file system.  Use WRKLNK or
EDTF to play around a bit, and you'll see how it works.  It can take some
time to access the complete list of servers in QNTC, since each entry must
be validated. Below is a doc that explains this.....

Document Title
QNTC File System Windows NT 4.0/2000 Server Discovery

Document Description
When drilling down through WRKLNK (Option 5) on QNTC file system, the list
that is generated from the network is gathered by the NetServer instance on
the hosting OS/400 platform from the configured Master Browsers/WINS
servers. This provides an unverified list of servers to the QNTC file
system. The buffer to receive this list is approximately 1k (about 12
servers). If the list is larger than the buffer, the buffer is multiplied by
4 (to about 50 servers) (over and over until the buffer is big large enough
to handle the list of servers). There is no limit to the number of servers
that will be displayed under the QNTC file system.

Before the list of servers is displayed under the QNTC file system, the
system queries each server in the list from NetServer to determine if it
supports the NETLOGON Service. This query verifies that each server answers
the NETLOGON service. If the server does not support NETLOGON, it will take
30 seconds to time out the query and move on to the next server. Therefore,
a network environment that has 600 servers, of which there are 300 that do
not support NETLOGON, powered off, otherwise disconnected, or unavailable,
will take approximately 2.5 hours to return a list of servers for a QNTC
query.

Note: Any network timing issues will add to the delay.
