Unsure of internal adaptor make. Running on NT server. All of a sudden, can send data but not recieve. When trying to send data to own number which always used to work, I get number busy. Had a virus file called Winno on desktop which I cleared. Could it be a faulty adaptor? Running on both channels @ 128k. Please someone help. I don't have any additional technical details at the moment, just some guidelines would be great. Thanks.
