DNS error 1000
We have dns server the same server active directory but some time error and some time dns crash about 1 hour do affect all application . how to know what do dns crash as query from client high ? ...
Hard to say for sure on this one but the simplest safest solution here is to stand up a new one for replacement, and move on.
I'd use dcdiag / repadmin tools to verify health `correcting all errors found` before starting `any` operations. Then stand up the new one, patch it fully, license it, join existing domain, add active directory domain services, promote it also making it a GC (recommended), transfer FSMO roles over (optional), transfer pdc emulator role (optional), use dcdiag / repadmin tools to again verify health, when all is good you can decommission / demote old one.
for Active Directory can change IP address because i want change AD new one to old IP
Sure, that's absolutely not a problem.
