Does anyone know if the STK100 (with Atmel AVR ISP) should work under Windows 2000? If not, any other recommendations for Win2k programming of ATTinys and 2343s?

I haven't had the oportunity to try programming the STK100 under Win2k, but I haven't had any other problem reports on this issue, either. The STK200/300 version of the AVR ISP software has well-known issues, but the STK100 has a special version called 3.31 available here. Is this the AVR ISP version you're using?
Of course, my recommendation for programming the ATtinys and 2343's (and indeed any other AVR with the current exception of ATmega103) is the AVR Studio/STK500 package. I think postings further down in the forum will confirm my view. But I understand you don't want to spend money on new hardware. There are several issues with the STK100 itself. The first that springs to mind, is the programming cable. The parallel cable must be as short as possible to avoid noise. Also, when programming the ATtiny15, it's a good idea to remove the SOUND jumper. Now that I think of it, I should just include a description of how to program the ATtiny15 with AVR ISP 3.31. There, done.
If I haven't been able to resolve any of your issues, I'm sorry. Please give me a bit more to work with regarding error messages and other symptoms in this case.

Not really sure why I got the stk100. I may have had trouble getting a stk500. If the support is much better on the stk500 I suppose I could return the stk100--it's new. I assume that win2k support for the stk500/avr studio is confirmed--yes?
I don't think it's the cable, because I can program successfully with the same machine (and cable) running win98 (dual boot). The only symptom I can provide is that AVR ISP gives an error message indicating that it cannot connect to the board. (Changing timeouts doesn't help.)
Two more quick questions while I've got you:
- I don't see a serial communication option in AVR ISP for the stk100, only for "ATAVRISP". Has support for this been removed since the stk100 manual was released?
- Is the stk100 a Kanda product?
Thanks for all your help,
The serial communication between AVR ISP and STK100 was never implemented, and yes, it's a Kanda product. The port handling in Win2k may be a lot different from Win98, and the parallel port is normally regarded as "difficult to use" by programmers under WinNT/2k (correct me if I'm wrong; I'm not a system developer). The STK500 uses the serial port, which is easier to handle. I've not heard of any problems with AVR Studio particular to Win2k.
From Atmel, the STK500/AVR Studio support is and will be prioritized above AVR ISP and obsolete development boards. Kanda is still supporting the older STKs, but they've released new versions (the "+" boards) with new software. I haven't tried this SW out, as I'm fine with my STK500 :)
I have win2k and an STK100. I too am having problems connecting it to the serial port - and the parallel port.
I must ask now what use this dev board is to me!
The code I write works OK using an ICE200 to the STK100, but the chip I program ( using another machine of course) fails to work correctly!
For what it's worth - I've attached it - and would love to know if it works in somebody elses Tiny11.
Simply causes the speaker on the STK100 to buzz up and down in varying rates continuously repeating.
Works fine on the ICE - but the programmed chip simply cycles through one fade only - very wierd!
