Thread Vista as a server
Thu, Aug 30 2007 11:10 AMPermanent Link

"Brian Kennedy"
Hello.  Unfortunately, we are having more and more customers running our
application over Vista and some problems are arising especially when using
Vista as the server.

As a test, we have installed the DBISAM database server on the Vista machine
as well as the DBISAM Database Utility for testing purposes.  Using the
Database Utility, when opening tables through the "Remote" connection, the
process hangs for 20-30 seconds and then the table opens.  It almost seems
like something is interfering with the opening of the table.

When we switch to open "Local" instead of remote, the table opens
immediately.  In addition, this lag does not occur when using XP as the
server with the Database Utility and remote connection.

Has anyone else experienced this lag when operating the server on a Visa
machine?  FYI, we have disabled the firewall and opened ports 12005 and
12006.

Thank you.

Sounds like the usual TCP timeout. Check networking is all okay.

Is there any anti-virus software installed ?
If so, then disable the DAT, BLB, IDX extensions from scanning.

Could it be this (from tim a while back)?


File-Sharing Issues with SMB2 and Vista
      

We just recently had a customer report an issue with using a Vista machine
sharing DBISAM tables with another Vista machine, and have found out that
there is a problem with using a Vista machine as a host for sharing DBISAM
or ElevateDB tables with other Vista machines due to a bug in the SMB2
protocol in the Vista OS.

For now, we recommend that you do *not* deploy any applications in such an
environment until MS comes up with an official fix. The indications are
that a fix will be available with the first Vista service pack. There is an
official hotfix available, but you have to call MS to get it and it isn't
publicly available.

You can find information on the problem here:

Major bug in Vista File Sharing (Peer-to-Peer)?

The problem only occurs with a Vista <--> Vista setup that can use SMB2.
With any other combination of OS's, such as XP <--> Vista or Vista <-->
2000, the problem doesn't occur because one of the participating OS's can
only use the SMB file-sharing protocol, not the SMB2 file-sharing protocol.

It sounds like something is definitely wrong on the Vista side in terms of
either a firewall or the network setup.  How long does it take to simply
establish a connection to the 12005 port using Telnet ?   If it takes just
as long, then there is an issue with the network layer.

That only applies to local (non-C/S) connections, so that wouldn't apply in
this case.
