A Citrix server that I manage suddenly stopped allowing ICA and RDP connections. The server is a HP Proliant DL580 G5, Windows Server 2003 SP2, 8GB RAM. Per the instructions in the knowledge base article on the Citrix website (CTX133141) I applied the Microsoft hotfix that claims to address the issue (WindowsServer2003-KB958476-x86-ENU.exe). Now the server restarts at random. The event log has the entry - System Failure: Stop error Reason Code: 0x805000f Bugcheck String: 0x0000008e (0x80000003, 0x8087358c, 0xf78c68d8, 0x00000000) Comment: 0x0000008e (0x80000003, 0x8087358c, 0xf78c68d8, 0x00000000) The memory dump appears to indicate an issue with the NIC driver - KERNEL_MODE_EXCEPTION_NOT_HANDLED (8e) Arguments: Arg1: 80000003, The exception code that was not handled Arg2: 8087358c, The address that the exception occurred at Arg3: f78d68d8, Trap Frame Arg4: 00000000 MODULE_NAME: bxnd52x FAULTING_MODULE: 80800000 nt DEBUG_FLR_IMAGE_TIMESTAMP: 48a27c40 Is there a known issue with the Microsoft hotfix? Should I remove the hotfix? Should I update the NIC driver? Not 100% sure if this issue is really caused by the hotfix or if this is a separate issue. Not sure what I should try first. Any help would be appreciated.

Hi, From reviewing KB958476 it would appear that the application of the hotfix was indeed correct. The fix seems to just address service start/stop settings which makes the BSOD issue puzzling. I would suggest that you first of all snapshot your machine using System Restore or whatever 3rd party tool you use, and then update the network drivers using the latest applicable ones available from the manufacturer website. Once installed and rebooted, test the environment again, should the issue still persist, try temporarily un-installing the hotfix, reboot and then re-install said hotfix. Kind Regards, Martin If you find my information useful, please rate it. :-)
