Guest Agrippa Posted November 16, 2007 Posted November 16, 2007 I am running Windows Server 2003 R2 SP1 on a domain with approximately 50 users all with Windows XP SP2. There is a domain controller and a backup domain controller. Periodically throughout the day random, but only one at a time, XP machines will lose access to the network shares while all other machines can continue to happily use the network. Network shares map to more than just one file server - ie, drive X will map to computer1 while drive Y will map to computer2. The user will lose access to ALL network shares. They will still be able to ping the computers by IP address or computer name, but the shared drive will say that it cannot connect and using the UNC name in explorer will fail. Once the share stops working the machine will be unable to connect to any machines through explorer. No machines will appear in my network places. Everything is fine once the computer has been rebooted, but it still might fail later in the day. Nobody likes this solution. On the servers, absolutely nothing is noted in the event viewer. On the client, it just notes which activity failed - ie, failed to write to a file that was open, etc. I think it usually gives an event id of 1005, but I'm not sure how important that is. It changes depending on what was open or trying to be performed. Thanks in advance!
Guest Jeff Stockamp Posted November 16, 2007 Posted November 16, 2007 Re: Losing network shares across multiple machines on Windows 2003 Are you running a firewall (windows or 3rd party) on either the clients or the servers? If so, you might want to try disabling it to see if that's the issue. You also might want to try going to a command prompt on a client that's having the problem and run "net use * \\server\share". That should report an error if it doesn't work. - Jeff "Agrippa" <royjones@gmail.com> wrote in message news:57aaf583-6d50-40ea-8da6-f7f7aceab7ac@d50g2000hsf.googlegroups.com... >I am running Windows Server 2003 R2 SP1 on a domain with approximately > 50 users all with Windows XP SP2.

Guest Newell White Posted November 16, 2007 Posted November 16, 2007 RE: Losing network shares across multiple machines on Windows 2003 We run an identical setup, except our two servers (both are file DSs and file-servers) are Server 2003 SP2. We do not suffer from this problem. FYI: 1) Both servers are WINS servers, DHCP distributes both addresses to workstations. 2) All servers and workstations have NETBIOS over TCP/IP enabled. 3) All workstations have browser service disabled so that Master Browser elections are rarely forced. -- Regards, Newell White "Agrippa" wrote: > I am running Windows Server 2003 R2 SP1 on a domain with approximately > 50 users all with Windows XP SP2.

Guest Agrippa Posted November 16, 2007 Posted November 16, 2007 Re: Losing network shares across multiple machines on Windows 2003 Thanks for the reply! "net use \\server" is reporting Error 1450: Insufficient system resources exist to complete the requested service. If I close the offending program sometimes I can regain access to the shares. These users are really hammering the file server(s) with a lot of files at once. The programs that are used, however, differ. Some are using Excel - others PaperPort.

Guest Agrippa Posted November 17, 2007 Posted November 17, 2007 Re: Losing network shares across multiple machines on Windows 2003 As an update to this problem, I think we've narrowed it down to Trend Micro's Client/Server suite. The software was adding 100 megs of paged kernel memory pushing the total memory use close to the 163 MB limit. After heavy use they'd reach the limit and the client computers would return the Insufficient Resources error when trying to access network drives. Thanks for the responses!

Hey, this problem sounds exactly like what I'm experiencing. What did you do? Did you just remove the Trend Micro Security Suite? Did it resolve the problem? can you please advise on what you did? thanks very much! dmgerst At gmail
Guest Agrippa Posted November 20, 2007 Posted November 20, 2007 Re: Losing network shares across multiple machines on Windows 2003 I think we've solved the problem. Trend Micro has suggested that we raise the maximum paged kernel memory allocated by adjusting the following key on the server and clients: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager \Memory Management Change (or add if not there) the following DWORD value: PagedPoolSize Set the value to FFFFFFFF (8 Fs). On our system the default was 0. This should roughly double the amount of memory allocated. Everything looks good so far. Good luck! > Hey, > > this problem sounds exactly like what I'm experiencing.
