Hi, I have a small home network on linksys router. Two w2k and one xp are networked, and they can ping each other. When I use 'net send' and it gives error: 'An error occurred while send a message to XXXX. The message alias could not be found on the network. More help is available by typing NET HELPMSG 2273.' I use ip instead of box name and got same error. The messenger service is on since there is an <03> entry. On the linksys router Filter: Block WAN Request: Enable IPSec Pass Through: Enable PPTP Pass Through: Enable L2TP Pass Through: Enable Remote Management: Enable Use default MTU: Enable I disabled Block WAN Request and net send still doesn't work. I don't have firewall. Can't figure out why, please help. Thanks. -wolf

Do you have the security permissions to allow you to send the Net Send message to the other workstations? Also check out MS Article Q263464 on the MS Knowledge Base...

Thanks for your reply. I'm on my home network, all pcs are peer to peer, and I don't know if it's the security permission problem. How to check it?
