SYMPTOMS
If a computer running Windows NT temporarily looses its physical connectivity (disconnection and reconnection of cable) to an ATM network, clients cannot re-establish a NetBIOS session without the server being restarted.



RESOLUTION
There is a new Olicom OC-615x driver, version 3.55 that resolves this problem. You can verify that the new version of the driver is loaded by running Olicom Adapter Information for Windows (AIW - this will be renamed to LanScout in the future) which came with the ATM adapter. Pressing F3 to generate a report.



MORE INFORMATION
The problem has been experienced with a computer running Windows NT 4.0 connected to an ATM network using an Olicom OC-615x (OC-6151 & OC-6152) with driver version 3.54. Olicom has confirmed that this is because of the way the driver reports the functional address to the NetBIOS stack when re- establishing the connection. Lower parts of the stack are unaffected, as the server still has TCP/IP connectivity.

This problem is also experienced in earlier versions of the driver.
