if you set scavenging on your zones then it will clear any stagnant records. Ipconfig /flushdns also clears DNS out and anything crucial will not be wiped, if it is, then it will auto populate back with dynamic addresses...i wouldnt eb too worried

but if it does wipe out critical things (such as our statically assigned servers) how would they repopulate?

if they are active records then i cant see them being wiped out, static ones wont repopulate as such, but they wont delete

i guess i just want to be SURE that scavenging or any other method won't wipe out major things like servers.  one other thing...in looking at DNS, found that scavenging is set up for reverse lookup, but not anything else...so it doesn't appear to be working, at least in the reverse lookup only zone.

so how confident are you jay jay70, about a scavenging not blowing out other static IPs?

Sorry with the half answers...got a couple of mins spare now,

Basically scavenging just removes state stagnant records, it doesn care if they are dynamically created or statically created, they are both the same in the end - simply records.....if you enable scavenging it will only delete old records that are not used at all.....so your static records if active wont dissapear - you wouldnt be using them at all if they were scavenged so it wouldnt matter.....

you could delete all entries from your zone (not internet records etc) and it would repopulate on the fly

hope thats a little clearer - back to work for me
