Risoluzione
DIAGNOSTIC STEPS
1. Enable verbose logging on the Password Manager Admin site (/PMAdmin)
2. Reproduce the issue and note the time of the issue.
3. Open the verbose log: “QPM.Service.Host…log”
4. Search for “DsQuerySitesByCost failed"
You may see the following lines in the log:
20xx-xx-xx 14:42:02:133 E [1608:23] QPM.Service.Modules.ADHelpers.dll DCHelper.GetSitesByCost() >> System.ComponentModel.Win32Exception (0x80004005): DsQuerySitesByCost failed with error 1722: The RPC server is unavailable.
(0x000006BA)
at QPM.Service.Modules.ADHelpers.NativeWrapper.DsContext.DsQuerySitesByCost(String fromSite, String[] toSites)
at QPM.Service.Modules.ADHelpers.DCHelper.GetSitesByCost(DsContext ctx, String closestSite)
5. Check if the time of the issue in the log matches.
RESOLUTION
1. If the issue happens with a new Domain that has never been added to Password Manager previously, the environment must be checked and verified. i.e. DNS, AD Replication
2. If the failed domain is present in the configuration of Password Manager you need to delete Default Domain Controller entry from the list of domain controllers.
This is located in PMAdmin | General Settings | Domain Connections | Edit button | Advanced Settings. Once removed, add a known good DC to the list from the DCs that are listed.
