Hi There,

I have SharePoint 2010 environment. I configured Word Viewing Service and PowerPoint service accordingly and all working perfectly. But recently it didn't work any more. I deleted services and recreate services, even stop and restart the service from Central Administration interface didn't make it working. I got same error message as below:

I found some suggestions from Google, and I did check the setting, but I didn't fix the problem.

Regards,

Tony

Can't see your error. You forgot to post it? Please update your question with error to provide you a solution.

Sorry Zak,

Here is the error message.

You must increase the permission on both service applications and then execute an IIS reset. Follow the steps explained in below article and you should get the error resolved.

Fixing Office Web Apps "Network Connectivity has been lost error"

As given in article...

1. Run this script in PowerShell:

Remove-PSSnapin Microsoft.SharePoint.PowerShell -erroraction SilentlyContinue
Add-PSSnapin Microsoft.SharePoint.PowerShell -erroraction SilentlyContinue

Write-Host -ForegroundColor White "--------------------------------------------------------------"
Write-Host -Foregroundcolor green "Fixing Word Viewing Service Application"
$e = Get-SPServiceApplication | where {$_.TypeName.Equals("Word Viewing Service Application")}
$e.WordServerIsSandboxed = $false
Write-Host -Foregroundcolor green "Word Viewing Service Application is fixed"
Write-Host -ForegroundColor White "--------------------------------------------------------------"
Write-Host -Foregroundcolor green "Fixing PowerPoint Service Application"
Get-SPPowerPointServiceApplication | Set-SPPowerPointServiceApplication -EnableSandboxedViewing $false
Get-SPPowerPointServiceApplication | Set-SPPowerPointServiceApplication -EnableSandboxedEditing $false
Write-Host -Foregroundcolor green "PowerPoint Service Application is fixed"
Write-Host -ForegroundColor White "--------------------------------------------------------------"

2. Do an IIS reset on SharePoint Application Server.

Note: Office Web Apps must be installed on a farm which uses a domain controller. For standalone installations this fix will not work. Before running this script please check the name of Word Viewing Service Application and PowerPoint Service Application because it may differ in your system. You can check it either from central administration site or by running Get-SPServiceApplication command.

Hi Zakir,

I did read this blog some time ago, and did run the script. Unfortunately it didn't work for me. The Office Web Apps was working, but there were something affected service. In my case the permission for the service account had enough right. I tried to create different services using different account such as using farm administrator or Application pool account, but I got same error. There are something else cause this error.

Hi,

For your issue, Check whether the PowerShell:

$e = Get-SPServiceApplication | where {$_.TypeName.Equals("Word Viewing Service Application")}
 $e.WordServerIsSandboxed = $false
 $e.WordServerIsSandboxed

#(Please use the below script for PowerPointServiceApplication - You need to enter "Y" for the answer of each cmd)
 Get-SPPowerPointServiceApplication | Set-SPPowerPointServiceApplication -EnableSandboxedViewing $false
 Get-SPPowerPointServiceApplication | Set-SPPowerPointServiceApplication -EnableSandboxedEditing $false

Hi All,

Thanks for all your suggestions, unfortunately neither of them is working for me. Currently I have Microsoft support involving this case, and the next step will reinstall Office Web App. I will let you know the process how to resolve this issue.
