What i discovered is, that the function that i need to use is: GetAdaptersAddresses, and it is contained in iphlpapi.dll library.
What would you recommend doing, when I can not find iphlpapi.dll on my device, as well as in: C:\Program Files\Common Files\Microsoft Shared\CoreCon\1.0\Target\wce400\armv4i. I chbecked system and hidden files as well. Could you send me this dll for XScale processor please, or give me some hint were to look for it

I am new to .net cf development, so my questions can be stupid/annoying, I'm sorry if it is like that.

I've checked if such a file exists on the device, by manual browsing, i could not find it.
Then I asked my friend to check if it is possibly contained within some other dll in win ce 4.2 platform. He has platform builder. He told me, that it is linked with other library: dminfos.dll, but i cant find it as well.
Device I am using is called: ViewSonic ASV38R-03. It has: Windows Mobile 2003 Second Edition. Version 4.21.1088 (Build 14235.2.0.0). The Device has Intel PXA27x processor.

You are right, thank you very much.
I was pretty sure that it is not there because i was browsing from my PC, and i was able to see system's dll files.
