Machine A and B are both running Win XP Home. Machine A is connected to the Net through an Ethernet card and cable modem. Machine B is connected to Machine A via a phone line LAN and through Machine A to the Net using ICS. Until a few days ago both machines could see and access shared folders/files in My Network Places. Now Machine A can see and access shared folders/files on Machine B, but Machine B cannot see shares on A. When a share is made on B, it appears in My Network Places on A after a short wait, but the reverse does not happen. Both machines can see each others shares when accessing the shares through the Entire Network/MS Windows Network/Work Group Name/Machine Name chain. B can print on a printer that is connected to A through the LAN. I have increased the DWord Value of the IRPStackSize from 11 to the default 15, which has eliminated the 'Not enough storage is available to process this command' error message we got initially. Net view shows the shares on both machines. Pinging both machines works. Enable Net BIOS over TCP/IP is on in both machines. LM Hosts is enabled on both. Printer and file sharing is on on both. Both machines can access the Net for browsing and e-mai retrieval. The LAN is configured with fixed IP addresses, 192.168.0.1 for A and 192.168.0.2 for B. I have searched the Knowledge Base and Googled to find the answer, but nothing to date has worked. Anybody know why shares show up automatically in My Network Places on A and not B?
