can you simulate a load over the weekend. Pausing printers, print then delete in a script multiple runas sessions copying files.
have you run perf mon logging everything 60 seconds aught to give you some data to look at. might show what resources are being used.

Then printing and file access just stops responding. No error events get recorded because nothing is being written to the logs. Thought this might be related to a bad RAID Array controller, so we replaced it and the same thing happened. We have added the registry entry suggested by Denise and will watch it over the weekend. Don't expect to know much until the Monday AM load hits.

Within the past two weeks, one of our main file and print servers has started to hang just like yours. We also noticed that the server would stop responding to request for up to 5 minutes then would come back. We thought it could have been a NIC issue so we moved the GIG cards and used the on-board 100, but it is still happening. One of the other things that I have seen in our logs is the event 2022 "Server was unable to find a free connection _ times in the last __ seconds" There is a article Q245080 that has a work around, but we have not tried it yet because I have seen this event for months and we have not had this problem before. js -----Original Message----- From: Sauer, Steve [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 26, 2001 6:01 PM To: NT System Admin Issues Subject: RE: File services hangs Denise, Thanks, i'll give this a try. I did not find any errors in the event log but this server has a high connection volume. It seems to hang either early in the morining, users connecting for the work day, or late afternoon, not sure what the users are doing then. Server has not crashed since yesterday morning, a new record 8^) Steve -----Original Message----- From: PITNEY,LDENISE (A-Sonoma,ex1) [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 26, 2001 12:27 PM To: NT System Admin Issues Subject: RE: File services hangs Hello Steve, You know, as strange as this sounds I had a problem similar if not exactly to this and found a fix. The machine kept tanking, and I noticed it seemed to just get confused but this registry entry fixed the machine and it's been rock solid ever since. What I found was that the server was running out of interrupt request packets (IRP's); the default value is 6 and that just seems to be too low if the connection volume for the machine is high. Check your event log and look for IRPSTACKSIZE errors. My server is a high-end HP net server [W2K OS] that does bit serving for our technical engineering windows-based apps and the user volume is 150-200 connections a day, 24 hrs a day, from all global sites in our company. Okay the fix is to increase the IRPSTACKSIZE buffer, using the registry editor. Here's the path: HkeyLocalMachine\System\CurrentControlSet\Services\lanmanserver\parameters So, create a New Dword value with the name IRPStackSize set the value to 11 Also, here's the TechNet article: Changes in IRP Stack Size in Lanman Server [Q198386] http://support.microsoft.com/support/kb/articles/Q198/3/86.ASP Good luck and let me know if it works for you. Best regards, Denise -----Original Message----- From: Sauer, Steve [mailto:[EMAIL PROTECTED]] Sent: Tuesday, September 25, 2001 3:59 PM To: NT System Admin Issues Subject: File services hangs Esteemed Colleagues, I have a Compaq Proliant 3000 server with a Pentium II 333 Mhz CPU and 128 Mb Ram running NT4.0 SP5. Access to file and print services has recently started hanging...on a daily basis. When the services hang I can't even log into the server or connect in any way using naming services. It has to be manually powered off to reboot. There are no traces of any problems in the logs. No evidence of Dr. Watson. I'm Stumped and at a loss of what to even look for in Technet or the archives. Very baffling. Regards, Steve Sauer Technical Lead - Systems Operations WIPP Site, Carlsbad, NM Want to unsub?
