Hello everybody. I'm new to this forum and this is my first post. I have this problem for a long time . When one IP is specified e.g. 192.168.1.166 mask 255.255.255.0 I can see network computers and their netbios names. But in our company my IP is 192.168.0.166 255.255.255.0 for intranet and 10.0.10.40 255.255.255.224 for internet access. My problem is when I specify second IP (10.0.10.40 255.255.255.224 gateway 10.0.10.49) I cannot any longer see computers in my network. The only way I can enter computer in network is to enter IP (e.g. \\192.168.1.165) or disable the second IP. There is one more thing. When only one IP is specified after computer restarts (192.168.1.166) and then I add second ip (10.0.10.40) everything works allright till the system restarts. In Windows XP everything worked OK. Problem is only in Windows 7. I think it's routing table problem but i'm not sure. I'll be very happy if somebody could help. Thanks. attachment : ipconfig /all Windows IP Configuration Host Name . . . . . . . . . . . . : KAROL Primary Dns Suffix . . . . . . . : Node Type . . . . . . . . . . . . : Broadcast IP Routing Enabled. . . . . . . . : Yes WINS Proxy Enabled. . . . . . . . : No Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : D-Link DGE-528T Gigabit Ethernet Adapter Physical Address. . . . . . . . . : 00-24-01-F1-43-2C DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes IPv4 Address. . . . . . . . . . . : 10.0.10.40(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.224 IPv4 Address. . . . . . . . . . . : 192.168.1.166(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.1.1 10.0.10.49 DNS Servers . . . . . . . . . . . : 83.175.180.1 83.175.180.30 Primary WINS Server . . . . . . . : 192.168.1.200 NetBIOS over Tcpip. . . . . . . . : Enabled Tunnel adapter Teredo Tunneling Pseudo-Interface: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Teredo Tunneling Pseudo-Interface Physical Address. . . . . . . . . : 00-00-00-00-00-00-00-E0 DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes Tunnel adapter isatap.{04CBFB34-A2E5-4FEA-B33B-C9EBC1B48FCC}: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Microsoft ISATAP Adapter Physical Address. . . . . . . . . : 00-00-00-00-00-00-00-E0 DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes attachment 2 - route print C:\Windows\system32>route print =========================================================================== Interface List 10...00 24 01 f1 43 2c ......D-Link DGE-528T Gigabit Ethernet Adapter 1...........................Software Loopback Interface 1 13...00 00 00 00 00 00 00 e0 Teredo Tunneling Pseudo-Interface 22...00 00 00 00 00 00 00 e0 Microsoft ISATAP Adapter =========================================================================== IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 192.168.1.1 10.0.10.40 276 0.0.0.0 0.0.0.0 10.0.10.49 10.0.10.40 276 10.0.10.32 255.255.255.224 On-link 10.0.10.40 276 10.0.10.40 255.255.255.255 On-link 10.0.10.40 276 10.0.10.63 255.255.255.255 On-link 10.0.10.40 276 127.0.0.0 255.0.0.0 On-link 127.0.0.1 306 127.0.0.1 255.255.255.255 On-link 127.0.0.1 306 127.255.255.255 255.255.255.255 On-link 127.0.0.1 306 192.168.1.0 255.255.255.0 On-link 10.0.10.40 276 192.168.1.166 255.255.255.255 On-link 10.0.10.40 276 192.168.1.255 255.255.255.255 On-link 10.0.10.40 276 224.0.0.0 240.0.0.0 On-link 127.0.0.1 306 224.0.0.0 240.0.0.0 On-link 10.0.10.40 276 255.255.255.255 255.255.255.255 On-link 127.0.0.1 306 255.255.255.255 255.255.255.255 On-link 10.0.10.40 276 =========================================================================== Persistent Routes: Network Address Netmask Gateway Address Metric 0.0.0.0 0.0.0.0 192.168.1.1 Default 0.0.0.0 0.0.0.0 10.0.10.49 Default =========================================================================== IPv6 Route Table =========================================================================== Active Routes: If Metric Network Destination Gateway 1 306 ::1/128 On-link 1 306 ff00::/8 On-link =========================================================================== Persistent Routes: None

If it works for XP and doesn't work for Win 7 , the the only diffrence that comes in mind is strong Host that enabled in Win7. Disable Strong host and see if that works. http://technet.microsoft.com/en-us/magazine/2007.09.cableguy.aspx Excute the following the commands on Windows 7 • netsh interface ipv4 set interface [InterfaceNameOrIndex] weakhostsend=enabled • netsh interface ipv4 set interface [InterfaceNameOrIndex] weakhostreceive=enabled
