Hi Jay...
You need to be using a Data ONTAP rev 5.3.4R2D2 or better (yes, I know.... we're still working on the C3PO release! :-)). You quoted a site server update propogation issue in your mail, but the root cause of that problem actually has to do with the way IIS uses the change notification APIs in Win32 (towit, very heavily!) and a small difference that existed between the way Windows NT handled change notify events and the way that Data ONTAP handled them. The issue was a little involved, and only ever occured when an app started using change notify like it was going out of fashion, but the engineering team here chased it down and it's all solved.
I did just try and check to make sure the needed fix got rolled into Data ONTAP 5.3.5 also, which you should be able to obtain from NOW, but the system we have for letting me do that doesn't appear to be available to me right now. I'll try again a little later and e-mail you privately.
