I am a Unix guy by trade, but my boss included me in a group to evaluate if it is possible to use Terminal Server and/or Citrix to replace conventional desktop PC's. I have found information indicating this is possible. But I have not found anything saying weather it is possible to run Terminal Server in parrallel across a WAN. Optimal situation for a failure or disaster situation would be to have a hot sight at one of our other locations. Does any one know if it is possible to keep two Terminal Server boxes mirrored accross a WAN and if so can you give me any insight as to how and where to start looking for information? Thanks in advance.
