I recently upgraded to Metaframe 1.8 for W2K; replaced all of the hardware also! My one MAJOR problem is in getting my modems (2) to answer; we use them (the modems) for dial-in ONLY. I did try adding RAS which does answer the call but Citrix still doesn't communicate with them. They are configured in Citrix as async devices. Citrix auto-configured them and I have removed and reinstalled them with the same setup as in the old server. The dial-in modems are Multitech MT5634ZPX-PCI with the latest drivers. This is running on a Compaq Prolient DL380 server (W2K - SP1, 640MB RAM). Also if someone could point me in the right direction for any good Admin books for Citrix on W2K!
