We are experiencing some very slow performance when attempting to
create a new program item from an application on a Windows-NT server.
Sometimes it takes as much as 30 to 45 seconds from the time that
we click OK to the time that the message advising that the "Path may
not be available" because it is a network drive. Interesting enough,
the same application copied to a Windows-NT Workstation with a share
comes back "instantly".
Windows-NT Workstation ---------> creates ICON from NT Server loaded
application is slow!
Windows-NT Workstation ---------> creates ICON from NT Workstation
loaded application is fast.
The network sniffer we are using is running in expert mode and is
reporting transmission delays. The message the sniffer gives is
WINDOW FROZEN
The TCP/IP Window of this station has been stuck at 8136 bytes for
longer than the "Zero Window" threshold of 5 seconds. The maximum
window size that has been observed is 8760 bytes.
The documented default for TCPWINDOWSIZE is 8760.
I noticed in one of my Microsoft courses that there is a registery
entry called TCPWINDOWSIZE which defaults to 8760, but when I look
into the registery under
HKEY_LOCAL_MACHINE\system\currentcontrolset\services\tcpip\paramters
the key does not exist. (Both Workstation and Server).
Does anyone have a clue why we are experiencing these delays from the
server only and if this registery value can affect this ?

Oops, it looks like it as IBM antivirus running on the server.
