I want to confirm more information with you:
- Is the user a local domain user?
- Have you set up a proxy using svrproxy01.acme.com?
- Will this issue still occur when other users are set as site collection administrators?
You could also check ULS logs or Event logs for further troubleshooting.
Also, try using powershell to create a site collection and compare the results:
Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue #Configuration Variables $SiteCollURL = "http://intranet.crescent.com/sites/Sales" $SiteName = "Sales Team Site" $SiteOwner = "Crescent\Salaudeen" $SiteTemplate = "STS#0" #Team Site Template #Create new Site Collection New-SPSite -URL $SiteCollURL -OwnerAlias $SiteOwner -Template $SiteTemplate -Name $SiteName
