Office 2010 powerpoint cannot open documents shared by Samba

[RisingYoung-Learn]

Describe what you noticed and did

1. Install Samba software on CentOS 7.6 (for example: the IP address is 192.168.53.176), and the /etc/samba/smb.conf file is as follows: [homes] comment = Home Directories valid users = %S, %D%w%S browseable = Yes read only = No inherit acls = Yes writeable = yes public = yes

2. Execute the following command in Windows to mount the Samba shared disk: NET USE "H:" \192.168.53.176\test_user test_passwd /USER:test_user /PERSISTENT:NO

3. Start cmd in Sandblxie and enter the following command: "C:\Program Files\office2010\Office14\POWERPNT.EXE" "H:\111.ppt"

4. Unable to open the file 111.ppt, the following error is reported:

   

5. The above operations, without using Sandboxie, directly use powerpoint to open the 111.ppt file normally;

Try unchecking this option:

(or change BlockNetworkFiles=y in the ini to BlockNetworkFiles=n)

[RisingYoung-Learn]

Try unchecking this option:

(or change BlockNetworkFiles=y in the ini to BlockNetworkFiles=n)

thank you for your reply! After adding BlockNetworkFiles=n in Sandboxie.ini, the problem remains.

Delete Template=BlockPorts because it blocks SMB ports as follows:

NetworkAccess=*,Block;Port=137,138,139,445
