Because there is minimal configuration overhead (from an Office Web Apps perspective) and zero data loss, there is little risk to rebuilding a farm. These steps can be a legitimate part of an action plan for resolving technical issues with Office Web Apps.
1. Take farm offline (if there is a load balancer)
2. Collect the current Farm information via Powershell (on WAC Server):
Get-OfficeWebAppsFarm > c:\MyWACfarm.txt
3. (If multi-server farm) use Powershell (on WAC Servers) to remove each child machine from the farm, then remove the parent machine. This will delete the farm.
4. Reboot the Office Web Apps server(s).
5. Recreate the farm via Powershell (on WAC Server) using (if appropriate) the parameter values from "MyWACfarm.txt".
New-OfficeWebAppsFarm -InternalURL "http://WACServer.corp.contoso.com" -AllowHttp -EditingEnabled -OpenFromURLEnabled
6. Reunite the children with their parent via Powershell (on WAC Server). Run this from each child server:
New-OfficeWebAppsMachine -MachineToJoin <ParentServer>
7. Bring farm back online.
Note: You may want to rebuild the bindings via SharePoint Powershell (on SharePoint Server):
Remove-SPWOPIBinding –All:$trueNew-SPWOPIBinding –ServerName “WACServer.corp.contoso.com” -AllowHttp
Note: Anything above in Red you need to replace with the correct information from your farm.
Configure Office Web Apps for SharePoint 2013http://technet.microsoft.com/en-us/library/ff431687
is it possible to use a wildcard certificate when publishing externally over https? we have one for our SharePoint 2013 farm eg *.contoso.com and I want to use the same certificate for our office web apps server - eg. oweb13.contoso.com
Hi Chet. Wildcard certificates are not supported with Office Web Apps Server. Please see the following:
•The FQDN in the SAN field can’t begin with an asterisk (*).
I use wildcard cert with no issues at all!
Boblar can you share a little more on your certificate configuration, we would like to do the same.
Brilliant. After hours of hunting articles and trying them to no avail, this worked for me. However, Microsoft SharePoint developers and managers have a lot to answer for. SharePoint is so unstable I find I spend more than half my time fixing things that
should work. This is really really really baaaaddddd!
