Narrative:

Shift was uneventful until about XA15 to XA30 when I began receiving several different forms of communication regarding ATC nadin flight planning system failure; NOTAM system update outage; and our situational display systems not receiving updates. With no clear information available; I started calling my stations to advise them of the potential problems; began reviewing each of my morning flight's NOTAMS and flight plans; and calling the different ARTCC flight data positions to see which flights had valid flight plans on file and which required manual coordination. At about XA30 I was able to listen in on the ATC special conference setup to coordinate and disseminate information regarding these situations and sometime before XB00 we received fax numbers so we could send flight plan information to ATC for manual entry. From XB00 to XB15 I was briefing my relief for shift turnover. At approximately XB05 I re-reviewed several mels; ensuring I had applied an MEL thrust reverser weight restrictions; updated enroute weight penalty screen; added MEL fuel as required; and reviewed landing limits in the program. I checked weather and landing limits at destination due to MEL sections; but failed correctly apply the most obvious; an inoperative thrust reverser which is a no go item to the destination airport. I also failed to reprint and updated turnover for my relief indicating this flight had these MEL items. On returning to work the following day I learned of my mistake and that corrective action was required and taken by my relieving dispatcher; for which I am very relieved and grateful. This was an embarrassing lapse of my responsibility. A busy shift and un-normal operations are no excuse for putting my name; on a release until I have 'taken the time' to ensure everything is done correctly. I was taught a long time ago the busier it gets; the slower you work. Because that's when you have less time to correct mistakes and do things more than once. I am reviewing my work flow and work habits to be sure that this type mistake does not happen again.
