8 решенийFlush DNS Cache
🤖 AI Analysis
"The user is experiencing issues accessing specific websites, while most others work fine. This suggests a potential DNS resolution problem. Flushing the DNS cache is a common and effective first step to resolve such issues by forcing the system to get updated DNS records."
Change DNS Servers
🤖 AI Analysis
"Similar to flushing the DNS cache, changing DNS servers can resolve issues where the current DNS server is having trouble resolving specific domain names. This is a strong candidate given the problem description of inaccessible specific sites."
Check Proxy Settings
🤖 AI Analysis
"Incorrect proxy settings can prevent access to specific websites, especially internal company portals. Since the user is on Wi-Fi and accessing a company portal, it's plausible that a proxy is involved and misconfigured."
Bypass Proxy for Specific Sites
🤖 AI Analysis
"If a proxy is indeed in use (as suggested by the previous solution), but is causing issues with specific sites, bypassing those sites through the proxy configuration is a direct solution to the problem."
Reset Network Settings
🤖 AI Analysis
"Resetting network settings can resolve a wide range of network connectivity issues, including those that might affect access to specific websites. It's a more comprehensive step but can be effective if simpler solutions don't work."
Renew IP Address and Release IP Address
🤖 AI Analysis
"Releasing and renewing an IP address can fix temporary network glitches that might be preventing access to certain resources. While less likely to be the primary cause for specific site inaccessibility compared to DNS or proxy issues, it's still a valid network troubleshooting step."
Temporarily Disable Firewall/Antivirus
🤖 AI Analysis
"Firewall or antivirus software can sometimes block access to legitimate websites. Temporarily disabling them is a good diagnostic step to rule out this possibility, especially for internal company portals which might be flagged by security software."
Check Firewall/Antivirus Logs
🤖 AI Analysis
"Checking firewall/antivirus logs can provide specific information about why certain websites are being blocked. This is a more advanced diagnostic step that can pinpoint the exact cause if security software is the culprit."
