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

178 New Member
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.loc al
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.

I have an Access 2000 application that has a backend database which sits on the network and a frontend installed to each PC.

I need to access some data on a server. I can access it directly using UNC (i.e. \\ComputerName\ShareName\Path\FileName) or using a mapped network drive resource (S:\Path\FileName).

Hi, I have an Access application installed on a network server that is accessed by several users. It isn't split into a front-end/back-end (I know it should be but when I've tried, the response time for all users is unacceptable). It has been working fine for many months, for all users. Recently, for one user, the response time has been unacceptable with a form taking 3-4 minutes to load that use to only take a few seconds.

Hi everyone. I have a very strange problem and I have no idea how to correct it. I created a VB.NET DLL that is used by several different apps for password file encryption/decryption. I have the original .NET DLL and I also built the DLL with a COM wrapper (the COM interop box checked in the project...) so it can be used with VB6 apps (or any other language for that matter). In order for a VB6 app to use this DLL, this control must...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
