Were running NowSMS & MMS gateway, the latest version. OS Name: Microsoft Windows 11 Enterprise OS Version: 10.0.26200 N/A Build 26200 OS Manufacturer: Microsoft Corporation Having an issue with MMSC crashing. The service shows running but in the windows logs we get these errors. Also when you see if 25 or 8080 is listening, its not or will not answer to telnet tests. Uninstalled / wiped NowSMS directory and reinstalled... Same issue. Any Idea? John Bittner Xaccel Faulting application name: MMSC.EXE, version: 0.0.0.0, time stamp: 0x59735850 Faulting module name: SMSUSER.dll, version: 0.0.0.0, time stamp: 0x59735850 Exception code: 0xc0000005 Fault offset: 0x00002840 Faulting process id: 0x1FA4 Faulting application start time: 0x1DCCC3775173375 Faulting application path: C:\Program Files (x86)\NowSMS\MMSC.EXE Faulting module path: C:\Program Files (x86)\NowSMS\SMSUSER.dll Report Id: 1147984b-d3a7-4400-bab5-a02fad070f57 Faulting package full name: Faulting package-relative application ID: Fault bucket 1609342757917492117, type 1 Event Name: APPCRASH Response: Not available Cab Id: 0 Problem signature: P1: MMSC.EXE P2: 0.0.0.0 P3: 59735850 P4: SMSUSER.dll P5: 0.0.0.0 P6: 59735850 P7: c0000005 P8: 00002840 P9: P10: Attached files: \?\C:\ProgramData\Microsoft\Windows\WER\Temp\WER.8dc6ddd6-5c22-48ad-b936-2fa03317b2f6.tmp.dmp \?\C:\ProgramData\Microsoft\Windows\WER\Temp\WER.34a014aa-cad6-417e-bb2b-28a4f858456e.tmp.WERInternalMetadata.xml \?\C:\ProgramData\Microsoft\Windows\WER\Temp\WER.c71de3cb-0f02-44ad-a967-245a59c17e63.tmp.csv \?\C:\ProgramData\Microsoft\Windows\WER\Temp\WER.088b9037-2760-4f17-aebd-b9b5c1f0e9ba.tmp.txt \?\C:\ProgramData\Microsoft\Windows\WER\Temp\WER.ddac302b-1439-4dec-847d-e42a11a29492.tmp.xml These files may be available here: \?\C:\ProgramData\Microsoft\Windows\WER\ReportArchive\AppCrash_MMSC.EXE_2afb1a1ebb7a8f48f75e546fc7945ad903f29ec_f6e536e6_48611f96-85c4-4a1c-b7c3-19336877e457 Analysis symbol: Rechecking for solution: 0 Report Id: 98a0e9fb-c008-403d-a769-849760b44675 Report Status: 268435456 Hashed bucket: 70c4ed83cd5190ba565588b62f850395 Cab Guid: 0 | |||
