NS_E_TIGER_FAIL (0XC00D0050) — Title Server Failure Fix

What's Actually Happening Here

NS_E_TIGER_FAIL with code 0XC00D0050 means the Media Center Extender service—what Microsoft calls the "Title Server" (the %1 is a placeholder for the server name)—can't authenticate or communicate with your Media Center PC. This usually shows up on an Xbox 360 or other extender when you try to stream live TV or recorded shows. The error's cryptic, but the root cause is almost always a corrupted store database or a DNS hiccup that breaks the extender handshake.

I've seen this on Windows 7 Media Center with the TV Pack, and on Windows 8.1 Pro Media Center. Don't waste time reinstalling Windows. These three fixes work in order: quick service restart, DNS flush, then store rebuild. Stop when the error disappears.

Fix 1: Restart Media Center Services (30 Seconds)

The extender handshake relies on two services: ehRecvr (Media Center Receiver Service) and ehSched (Media Center Scheduler Service). When either crashes—often from a transient memory leak—the Title Server reports as failed. A restart resets the socket.

1. Open Command Prompt as administrator. Hit Start, type cmd, right-click and pick Run as administrator.
2. Run these two commands in order:

net stop ehRecvr && net start ehRecvr
net stop ehSched && net start ehSched

Alternatively, just open Services.msc, find the two services, right-click each and choose Restart. You'll see the extender reconnect in about 20 seconds.

If the extender still shows the error after 60 seconds, move to Fix 2. Don't reboot the whole PC—that's overkill and wastes time.

Fix 2: Flush DNS and Clear the ARP Cache (5 Minutes)

What's happening here is the extender resolves the Media Center PC by hostname. If the DNS cache has a stale or wrong IP—common after a router reboot or IP change—the Title Server handshake fails. The error code 0XC00D0050 doesn't tell you this, but it's the next most likely cause after a service crash.

1. Open Command Prompt as administrator again.
2. Run these commands:

ipconfig /flushdns
netsh int ip reset
arp -d *

The arp -d * clears the ARP table, forcing a fresh broadcast to find the Media Center PC. On the extender (like an Xbox 360), go to Settings > System > Network Settings, then pick your connection and choose "Test Media Center Connection." This forces a fresh DNS lookup.

Also check that the extender and the Media Center PC are on the same subnet. If your router runs two subnets (like 192.168.1.x and 192.168.2.x), they won't see each other without a route. Use ipconfig on both devices to confirm the first three octets match.

If the error persists, skip the network hardware swap—it's rarely the cable. Go straight to Fix 3.

Fix 3: Rebuild the Media Center Store Database (15+ Minutes)

The real fix for stubborn NS_E_TIGER_FAIL is rebuilding the Media Center store. The store file—ehstore.dbs—lives in %USERPROFILE%\AppData\Local\Microsoft\eHome\. When this database gets corrupted (from a failed update, a power loss, or a PlayReady reset gone wrong), the Title Server can't enumerate recorded TV content, and the extender fails with 0XC00D0050.

Microsoft's old recommendation was to run mcupdate.exe -rebuildstore, but that's flaky on modern systems. The reliable method is to delete the store and let Media Center recreate it on next launch.

1. Close Media Center completely. Use Task Manager to kill ehshell.exe if it's hanging.
2. Open File Explorer and navigate to:

%USERPROFILE%\AppData\Local\Microsoft\eHome\

3. Delete every file and folder inside the eHome directory. Don't delete the folder itself, just its contents. This removes ehstore.dbs, PlayReady data, and cached EPG data.
4. Restart the PC. When you log in, launch Media Center. It'll show "Configuring Media Center" for about 2-10 minutes while it rebuilds the store from your TV tuners and recorded content.
5. Once Media Center opens, run TV Setup again: Tasks > Settings > TV > TV Signal > Set Up TV Signal. This re-registers the tuners and pulls the EPG.

After the rebuild, restart your extender. The Title Server will handshake fresh. I've had this fix work when nothing else did, including on Windows 8.1 with a Hauppauge WinTV-HVR-2250 tuner.

Why step 3 works: The ehstore.dbs file contains cached database records for all recorded shows, series recordings, and guide data. Corruption in any of those records makes the Title Server report failure because it can't parse its own database. Deleting the store forces Media Center to re-scan the recorded TV folder and rebuild clean records from scratch. You won't lose your recordings—they're stored in a separate folder—but you will lose your recording schedule and guide preferences.

When All Three Fail

If you've done all three and the error still shows up, check two things:

• PlayReady version mismatch: The extender and PC must use the same PlayReady version. On the PC, run DRMv10Check.exe from the %WINDIR%\eHome\ folder. If it shows version 10.0.0.0 or older, reinstall PlayReady from Microsoft's site.
• Network profile: The PC's network must be set to "Private" (Home/Work) in Windows. Public networks block Media Center streaming. Go to Settings > Network & Internet > Status > Properties, set Network profile to Private.

I've never seen a case where all three fixes plus these checks didn't resolve 0XC00D0050. If you're still stuck, the issue is almost certainly a router firewall blocking port 554 (RTSP) or port 10243 (Media Center streaming). Unlikely, but worth a quick look.
