ISOs are mostly errors caused by caching - the above should address the file corruption occuring due to NT-style deferred writes and caches. There are slightly different hacks for Citrix.
In addition, these hacks need to be applied to the -host- server for the data as well as the TS box(es) - it does no good just to alter these settings on the TS box if the data resides on another server, who can be just as guilty of caching things poorly.
