hi guys
I have an odd query which i need some help with pls...
I have 3 virtual servers.
1x domain controller (internal: 10.10.4.5)
1x fs01 file server (internal: 10.10.4.7)
1x app01 server (rds) (internal: 10.10.4.6)
All have pertino VPN client installed so users can access the APP01 and FS01 resources from anywhere.
The servers have internal IP's (shown above) but also have an IP from Pertino on a 172.86.160.X range.
Recently weve run into problems where random people at random times cant access the servers (not all at the same time. ie totally random). someones it may be 5 users cant access one server, but everyone else can, then another 10 users cant access another server but everyone else can and so forth - its random.
ive checked event viewer and see this error recently which i think is related....
The system failed to register pointer (PTR) resource records (RRs) for network adapter
with settings:
Adapter Name : {7F022283-1684-4AF5-AC79-07855C065DEA}
Host Name : app01
Adapter-specific Domain Suffix : hq.MYDOMAIN.local
DNS server list :
10.10.4.5
Sent update to server : <?>
IP Address :
10.10.4.6
The cause was DNS server failure. This may be because the reverse lookup zone is busy or missing on the DNS server that your computer needs to update. In most cases, this is a minor problem because it does not affect normal (forward) name resolution.
If reverse (address-to-name) resolution is required for your computer, you can manually retry DNS registration of the network adapter and its settings by typing 'ipconfig /registerdns' at the command prompt. If problems still persist, contact your DNS server or network systems administrator. See event details for specific error code information.
Do i need to configure something in DNS?
I manged to resolve the issue once i restart the Pertino services on the 'broken' server and then it works but it keeps happening and I need to fix it permanently. I have disabled IPV6 on all servers and on the Pertino adapter as i used to get IPV6 replies when pinging which I didnt want.
PLEASE CAN YOU HELP? I'm not sure how to go about this one.
Thanks
