PC's on network keep losing access to mapped network drive

[cleary1981]

Hi All,

I have a windows 2003 server and a number of machines runing XP. I have a vigor 2820 router as my DHCP server for a range 160-200. Most of my PC's are on fixed IP outside this range with no conflicts. The trouble is almost every day at least one machine will lose access to a mapped network drive on the server. The user is then prompted for login credentials to restore the mapped drive but their credentials do not work. Logging off and back in resolves this issue but it is becoming a real pain.

Anyone any ideas?

Thanks in advance.

I think the most useful messages as to why this is occurring would be in the logs on the machine that just lost connection.

Is this an Active Directory configuration (domain)?

I found this in the system log. It is an active directory configuration.

The system failed to register host (A) resource records (RRs) for network adapter
with settings:

Adapter Name : {0226CAF3-833C-476B-8581-5E700BCB1DCE}
Host Name : Design_office
Primary Domain Suffix : TES-Engineering.local
DNS server list :
192.168.2.1
Sent update to server : <?>
IP Address(es) :
192.168.2.30

The reason the system could not register these RRs was because the DNS server contacted refused the update request. The reasons for this might be (a) you are not allowed to update the specified DNS domain name, or (b) because the DNS server authoritative for this name does not support the DNS dynamic update protocol.

To register the DNS host (A) resource records using the specific DNS domain name and IP addresses for this adapter, contact your DNS server or network systems administrator.
