Multiple PCs With Same IP Address in DNS - CANNOT get Scavenging to Work! :(

[JRA]

Okay this has been the work of years. Tweaking, never right, tweak again, never right...

 

Can anyone who's got any knowledge this way help me stop this? I just don't know what it wants from me.

 

Multiple PCs in DNS are getting the same IP addresses and both pinging etc. This is killing me.

 

Can anyone just let me know what the thing wants from me? Is this DNS or DHCP scvenging at all even?

 

I'm so flipping lost...

With my bravery hat on I went into DHCP and checked all the sensible DHCP > IPv4 > properties > DNS bits:

 

 

On one of the DHCP servers the bottom tickboxes were greyed out, and "Always dynamically update..." now set on both DHCP servers, and both servers now set to these options here.

 

Hopefully that does something. Don't think it'll make it worse at any rate.

Why do you have multiple DNS servers? surely you should only have one...

Heh, no got three of them in fact.

Actually that seems to have REALLY shifted it into gear. Goodness. Scavenging no-refresh and refresh times in DNS both set to 1hr, IP addresses looking VERY tidy, no duplicates.

 

I wonder that that's TOO aggressive but in a perverse way I look at it and think "yeah you GET busy at that after four years of flipping slacking..."

 

Hopefully that's not idiotic in any way. At least my problem is fixed.

 

I need a holiday or something...
