Need info about route.exe

[bigjeff314159]

does anyone know anything about route.exe? all i can find out about it is that it's a system 32 application that runs from a prefetch routine. if i don't get on the internet immediately after power-up or restart this rascal will run for about 10 seconds (using 100% cpu) about every minute. if left alone it'll eventually run for 30 seconds (or more) every minute and crash any running apps. (because of its 100% cpu usage). ad-aware and anti-virus turn up nothing. win xp home on p4 1.5. i can live with this but i'd at least like to know what purpose route.exe serves.

thanks, big jeff

"4. ROUTE.EXE

Route is used to view or modify the route table. Route print displays a list of current routes known by IP for the host. Route add is used to add routes to the table, and route delete is used to delete routes from the table.

In order for two hosts to exchange IP datagrams, they must both have a route to each other, or use a default gateway that knows of a route.
Normally, routers exchange information with each other using a protocol such as Routing Information Protocol (RIP) or Open Shortest Path First (OSPF).

Routing is the primary function of IP (I mean IP as its singlar part of the TCP/IP protocol suite. See RFC 791).

Datagrams are handed to the IP protocol from UDP and TCP transport above, and from the NIC(s) below (see the OSI Networking Model). Each datagram is labeled with a source and destination IP address. The IP protocol examines the destination address on each datagram, compares it to a locally maintained route table, and decides what action to
take. There are three actions which can be taken for each datagram.

1. It can be passed up to the protocol layer above IP on the local host (ie: On to an application running on the machine).
2. It can be forwarded by one of the local NIC's (sent out onto the network via a network device).
3. It can be discarded.

The route table maintains four different types of routes.
1. host (a route to a specific destination IP address)
2. subnet (a route to a subnet)
3. network (a route to an entire network)
4. defualt (used when there is no other match)

Hope this wasnt too technical (even though its actually a very brief overview). I learnt all this from Microsoft Whitepapers, Microsoft MSCE study guides and RFC's."
