What you’re seeing
- The Windows Security log shows thousands of Event 4625 entries per hour with logon type 10 or 3.
- Failed attempts target common names such as administrator, admin, user, scanner or test from IP addresses you do not recognize.
- Real user accounts get locked out repeatedly with no one having mistyped a password.
- The server feels sluggish and Remote Desktop connections are slow or time out.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- Remote Desktop is published directly to the internet through a port forward on the firewall.
- Automated bots scan the internet for open RDP ports and try leaked or common passwords around the clock.
- Account lockout thresholds are missing, so attackers can guess without limit.
- No VPN, gateway or multi-factor layer sits in front of remote access to the server.
- Weak or reused passwords exist on the server, which keeps it attractive to attackers.
Why it matters
Exposed RDP is one of the most common ways ransomware gangs get into small businesses. Every failed attempt is a sign the server is being actively targeted, and only one correct guess is needed. Even before a breach, lockouts interrupt staff and the constant traffic slows the server. If an attacker gets in, the result can be encrypted files, stolen data, ransom demands and days of downtime.
How AskTechGurus fixes it
Skip the trial and error. A certified engineer works on your actual system, finds the root cause, and fixes it properly.
Tell us what’s happening
Submit a ticket in about two minutes. Paste the error, describe what changed, and pick your tier. No charge to submit.
A certified engineer diagnoses it
A vetted, US-based systems engineer claims your ticket, usually within minutes during business hours, and investigates over a secure remote session you can watch and end at any time.
Fixed and verified with you
The engineer resolves the root cause and confirms with you that it’s working. You don’t just get a workaround, and you get a plain-English summary of what was wrong.
Pay only when it’s resolved
Fixed price from $99, invoiced only after you approve the fix. If it isn’t resolved, you don’t pay.
Frequently asked questions
Has someone already gotten in?
Failed logons alone do not prove a breach, but the same logs should be reviewed for successful sign-ins from unfamiliar addresses. That review is the first thing to do before assuming you are safe.
Can you stop the attack without cutting off our remote workers?
Yes, that is the usual goal. Our certified US engineers work in a remote secure session to secure remote access while keeping staff able to connect, and you pay only when it is resolved.
