Hey all, having an issue here and I hope you can help. I'm running a web and exchange server. Both running Microsoft Windows Server 2003. I recently had an issue reported to me. Apparently our website wasn't working without the www in front of it. So(on exchange server), I went into the MMC(start-run-MMC) and added the DNS snapin. I have two domain controllers and exchange is one of them. I expanded Forward Lookup Zones and selected my domain. I myself didn't create this network originally, but I manage it now. I noticed that there were several Host (A) entries for the (same as parent folder) entry which from my understanding indicates the forwarding path of the domain without a prefix, IE www.
So, I made note of those forwarding paths and their settings, backed them up, and removed them, leaving only one forwarding path, to the public IP for the actual website. I tested this and it didn't work instantly, but strangely enough it worked after about 15 minutes, despite the fact that I cleared the IE cache on the computer I was trying to use.
All was well and good until today when the same issue popped back up. I went back into the DNS snapin and discovered some of those forwarding paths had been readded. I'm assuming they replicated from my other domain controller? I'm not sure what the deal is. I deleted them again, and once again after 15 minutes I was able to follow my non-prefixed domain back to my actual webpage.
Also, I haven't tried this webpage externally today. I'm trying it from my network. I'm pretty new to website development and management in general, and I didn't know what the folders DomainDnsZones and ForestDnsZones indicated. Is it possible some of the entries are replicating from these folders, or perhaps the replication is in my mind, and inner network forwarding zones are simply different than the DNS Host (A) type entries entered under the standard domain. One more note, I use the same domain to manage an intranet and a web-based outlook email system via exchange, with different prefixes.
Basically, I'm fixing this, but it won't stay fixed. Sorry about the convoluted explination, incorrect assumptions, and exceedingly poor grammar, any thoughts?
