| During testing of the LAN redundancy
feature it was found that if you power up the a computer with a DEC
PCI Ethernet DEC chip 21040 network adaptor and the 10 BASE T cable
is removed Citect will not be able to communicate when you plug the
cable back in. However you can still connect to a file server once
you plug the cable back in. This was seen running Windows 95
talking to a Windows NT file server. This appears to be a problem
with the auto detection of physical media of the DEC card and the
booting of the NetBIOS interface on Windows 95. As the Windows 95
redirector does not use the NetBIOS API it seems to bypass this
problem as that appears why you can still communicate to the
network file server.
You can verify this problem by using a network protocol
analyser. On startup and every 30 seconds the Citect client will
try to connect to the Citect server, on a network protocol analyser
you should see the calling protocol packets. When this problem
occurs you will see no network packets. If you see this problem you
must turn the computers power off and power on with all network
cables attached.
This could also be a problem with other auto sense network
cards. It is recommended that you always boot up the computer with
the network cables attached. See also Q1888.
