Common emergencies we handle
Most calls are about one of these. If yours isn’t on the list, call anyway — most outages have the same shape underneath.
Email outage
Microsoft 365 not delivering, mailboxes locked out, or DKIM/DMARC suddenly failing on outbound.
Server or NAS down
Production server unresponsive, ESX host alarming, file shares offline, or backups not running.
Ransomware indicators
Files renamed, ransom notes, EDR alerts, or staff reporting locked desktops. Time matters.
Account compromise
Suspicious sign-ins, MFA bypass attempts, finance fraud emails, or vendor invoice changes.
Network or ISP issues
Whole site offline, slow VPN, firewall throwing rules, or wireless dropping clients across the office.
Phones or VOIP
ShoreTel, Teams Phone, or generic SIP system not registering or routing inbound calls properly.

Why call us instead of someone else
Local accountability
Headquartered in Troy, MI. The person you talk to is the person responsible for solving it. No call-center routing.
Operator-led, not sales-led
Founded by a 20-year manufacturing IT director and USMC veteran. We've actually run the systems we support.
Modern security baseline
EDR, MFA, identity hardening, and backup discipline are part of how we work, not a separate upsell.
Service area
On-site response across Metro Detroit. Remote response anywhere in Michigan.
FAQ
Do I need to be a CoreITService client to call?
No. DetroitHelpdesk handles one-time IT emergencies and short-term work for any local business. If we're a fit for your ongoing operation, we can talk about the managed IT model on a separate call.
How fast can you respond?
For real emergencies during business hours, expect a callback in under 15 minutes. After-hours coverage is available at incident rates.
Can you work with our existing IT person?
Yes. Co-managed support is part of how we operate. We back up internal IT staff for projects, escalations, and after-hours coverage without trying to replace them.
What does emergency response cost?
One-time emergency engagements are quoted by scope. We don't lead with low-bid pricing — we lead with response time and outcomes. Typical incident remediation runs $500 to $5,000 depending on severity.
Right now is a good time to call.
If you’re reading this, something is probably already broken or about to be. Pick up the phone. Worst case, we tell you it’s a five-minute fix and you’re back to work.
