Unable to read / write Microsoft Office files on NAS due to access denied erros.
Last Updated December 16, 2016
When reading / writing Microsoft Office files on NAS, you run into an access denied error. At same time, the following error message can be seen in Application Log on Symantec Scan Engine (SSE) / Symantec Protection Engine (SPE) system:
The Scan Engine has encountered a scan error Date/time of event = 2013-05-13 15:49:24 Event Severity Level = Error Scanner = Decomposer Result ID = 37 URL = no_path File name = XX.zip Client IP = X.X.X.X Scan Duration (sec) = 0.000 Connect Duration (sec) = 43.243 Scan Engine IP address = X.X.X.X Scan Engine Port number = 1344 Uptime (in seconds) = 44922
Wed Aug 31 13:18:09 JST 2016 The Symantec Protection Engine has encountered a scan error Event Severity Level = Error Scanner = Generic Result ID = 6 File name = \\x.x.x.x\ONTAP_ADMIN$\vol\vol1\xxxxxxx.tmp Client SID = S-1-5-21-xxxxxxxxxx-xxxxxxxxxx-xxxxxxxxxx-xxxxxx Client IP = x.x.x.x Scan Duration (sec) = 0.000 Connect Duration (sec) = 0.000 Symantec Protection Engine IP address = x.x.x.x Symantec Protection Engine Port number = 0 Uptime (in seconds) = 660
This error could be observed in (but possibly is not limited to) integration of SSE / SPE with EMC Celerra / EMC VNX / NetApp DateONTAP systems.
Errors are related to an issue with meta data caching on SMB2-clients like SSE / SPE, possibly caused by the SMB2 redirector using Directory caching.
1. Please make sure following key doesn't exist (as it disables SMB2): [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters] "Smb2"=dword:00000000
2. Set the following registry keys on all SSE/SPE servers: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Lanmanworkstation\Parameters FileInfoCacheLifetime DWORD_32Bit 0 FileNotFoundCacheLifetime DWORD_32Bit 0 DirectoryCacheLifetime DWORD_32Bit 0
When done, please reboot SSE / SPE system(s). Please be aware this change is likely to increase traffic between NAS and SSE / SPE systems.
