The user is a customer of webtv. Checking on the HiPerARC verified this via the login information. 100a63010@webtvf-ip-I3055 IP slot:8/mod:7 ENA DYN 204.x.x.x/H While working too a very small degree with Microsoft they dropped the issue..so I for one am left with a puzzle on my hands. While the person is using our network equipment to access the net, the are not really a customer of ours. I reffered this information to Microsoft who would not look into it nor question the customer. I took it upon myself to contact the customer. The only real information they were able to offer me was that their WebTV box was acting with on the day of the detect I had and a few days later..after rebooting the box the customer had no further problems. This is a WebTV device, not WebTV for Windows. Anyone ever see anything similar to this, or have some decent explanation besides spoofing or tcp hijacking as Microsoft already gave us those and we have since disregarded those due to our network setup. - -Keith -----BEGIN PGP SIGNATURE----- Version: PGP 7.0.4 iQA/AwUBO4qrpuGTq6qVSXTQEQL//wCgolNxyde+hBW9KBedD/W6FHdOb2wAoLAU pXmAtCmmBLMgLVzWQM9RaePp =PTuG -----END PGP SIGNATURE-----
