How do I find packet size?

[RachelD]

How do I figure out what packet size is being used by my NT server? (using TCP/IP as only protocol)

TIA

Packet sizes vary greatly, depending on the type of TCP/IP traffic, not much at all on the operating system. I think you are probably confusing this with 'window size'. NT uses an 8,760 byte window size on Ethernet networks.

Other relevant figures include the MSS (Maximum Segment Size) and MTU (Maximum Transmission Unit). To explain how the window size is calculated based on these figures would be complex and boring, so I won't detail it unless you ask.

MSS is calculated by subtracting 40 bytes from your MTU. MTU typically depends on the type of network you are connected to, but it's commonly 1500 bytes. That might be the number you are looking for.

To learn more about TCP/IP parameters that are stored in the registry, look at 'regentry.hlp' which is a help file in the NT Resource Kit.

Why are you curious about packet size?

You're right actually - I did mean window size and am having one of those days where I get my words twisted! And once I realized I meant window size, I was able to actually find it when I tried to look it up and found the same answer you gave me.

thanks!
